Resistance Training After 40: Fight Osteoporosis & Rebuild Strength
Bone loss does not hurt. That is exactly the problem.
What you feel first is the muscle going. The grocery bags feel heavier than they should. The stairs take a breath longer. Getting up off the floor quietly becomes a two-step negotiation — one hand on the couch, then up. Most people blame being busy, sleeping badly, or just getting older, and by the time a scan puts a name on it — low bone density, osteopenia, early osteoporosis — the process has usually been running for years.
So is this simply the price of turning 40? Part of it is biology. But a large part of it is negotiable, and the negotiation tool is not a supplement, a scan, or a gentler life. It is load. Resistance training after 40 is not about chasing the body you had at 25. It is about protecting the two tissues that decide how independently you live at 65, 75, and beyond: muscle and bone.
THE SHORT ANSWER
Resistance training — lifting weights, using bands, or training with your own body weight against real effort — is the most practical, evidence-backed tool you control for slowing age-related muscle and bone loss. In supervised trials, it has also produced modest gains in bone density in adults who already had low bone mass.
For most beginners over 40, the effective starting point is two to three full-body sessions a week built around squatting, hinging, pushing, pulling, and carrying — light at first, then gradually heavier as technique improves.
If you have already been diagnosed with osteoporosis, or you have had a fragility fracture, this still applies to you. You just start smarter: medical clearance first, coached technique, and the guardrails laid out in the safety section below.
After 40, Muscle and Bone Start Leaving Together
Two quiet processes run in parallel from midlife onward. The first is sarcopenia, the age-related loss of muscle mass and strength. A widely cited review of muscle aging puts the loss at roughly 3 to 8 percent of muscle mass per decade after age 30, and the rate climbs after 60.
Nobody feels a percentage leaving. You feel it as a jar lid that fights back, a suitcase that changed weight over the summer, a grandchild who is suddenly heavier on the stairs than last year.
The second process is slower and completely silent. Bone mass peaks by about age 30; from there, breakdown gradually outruns rebuilding. For women, the estrogen drop around menopause speeds that loss for several years. Men lose bone more gradually, which is one reason it stays undetected for so long. The endpoint of that silence is the number the Bone Health and Osteoporosis Foundation keeps warning about: about one in two women and up to one in four men over 50 will break a bone because of osteoporosis. For many people, the fracture is the first symptom.
These two losses are not separate problems. Muscle is the engine that loads bone. Weaker muscles pull less, so bone receives a weaker signal to maintain itself. Weaker muscles also mean worse balance and slower reactions, and weaker bone means the fall that follows ends differently. That is the spiral — and taking it easy does not protect you from it. Taking it easy is what feeds it.
The body is giving you information, not failing you.
FROM THE COACHING FLOOR
From my coaching experience, almost nobody walks in worried about their bone density. They walk in because the stairs changed, the floor got further away, or they watched a parent go through a hip fracture and decided that story ends with them. Muscle is the alarm you can hear. Bone is the one you cannot. Training answers both alarms at the same time, which is why we start with strength long before we ever argue about numbers on a scan.
What Resistance Training Is — and How Your Bones Hear It
The plain definition
Strip away the jargon and resistance training means one thing: your muscles contract against an external force and work hard doing it. That force can come from dumbbells, a barbell, a cable machine, a resistance band, a kettlebell, or your own body weight. A push-up is resistance training. So is standing up from a low chair without using your hands. The equipment is the least important part; the effort is the message.
This is not about building stage muscles or living in the gym. It is strength as health insurance — enough muscle to move well, catch yourself when you trip, and keep loading the skeleton that carries you.
How bone hears the signal
When a muscle works against resistance, it pulls on the tendon anchored to the bone. That pull stresses the bone by tiny amounts. Cells buried inside the bone, called osteocytes, sense that stress and call for reinforcement. Builder cells known as osteoblasts then lay down new bone in the places carrying the most load.
That is Wolff's law in plain English: bone adapts to the loads placed on it. Load it consistently and, over months, it tends to become denser and stronger in the exact places being challenged. Unload it — a leg in a cast, a season in a chair, months in zero gravity — and the body promptly recycles what it thinks you no longer need.
Most people picture the skeleton as scaffolding: built once in youth, then slowly crumbling. It is not. Your skeleton is living tissue that removes and replaces itself across your entire life. Training does not create that process. It gives the process better instructions.
The evidence: older bone still answers load
Does this still work once bone is already thinning? In the LIFTMOR randomized trial, postmenopausal women with low bone mass trained twice a week for 30 minutes over eight months, lifting heavy under close supervision. Their lumbar spine bone density improved by about 2.9 percent, while a low-intensity exercise group lost about 1.2 percent over the same period.
Two details matter as much as the result: every participant was screened first, and every heavy lift was coached. That is the model this guide follows — serious load, never recklessness dressed up as motivation.
The practical answer is not "lift as heavy as possible, starting tomorrow." It is "start loading, start light, and earn heavier." Next, we look at what this training actually buys you beyond a density score, and at the five beginner mistakes that quietly cancel the benefits. Then you get the program.
What This Training Buys You Besides a Density Score
Bone density is the headline number. It is not the whole paycheck. Here is what consistent strength work tends to deliver in daily life for men and women over 40:
Muscle that keeps you independent. Muscle is not decoration. It is what gets you off the floor, out of a low car seat, and up the stairs with shopping in both hands. Resistance training is the most direct countermeasure we have against sarcopenia, and the gains show up first as function, long before they show up in a mirror.
Fewer falls, better saves. Most fragility fractures begin with a fall, not with a diagnosis. Stronger legs, hips, and grip give you a fighting chance to catch yourself mid-stumble. In a Cochrane review of exercise trials in adults over 60, programs built mainly on balance, functional, and resistance exercises cut the rate of falls by about 23 percent. Every single-leg exercise in this guide is a small deposit against that statistic.
A metabolic buffer. Muscle is the largest tissue drawing glucose out of your bloodstream, which is one reason strength work supports blood-sugar control. In a meta-analysis of cohort studies, muscle-strengthening activity was associated with a 10 to 17 percent lower risk of death from any cause, cardiovascular disease, and diabetes, with the strongest association around 30 to 60 minutes per week. People who train also tend to sleep, eat, and see their doctor differently, so read that as a strong association, not a personal guarantee.
Steadier sleep, steadier mood. Beginners consistently report sleeping more deeply and handling stress better within the first weeks. There is also something quietly powerful about watching a number go up — one more rep, one heavier dumbbell — at an age when you were told to expect every number to go down.
The Five Mistakes That Quietly Cancel the Benefits
The mistake I see most often is not laziness. It is good effort spent in the wrong order. Over years of coaching beginners past 40, the same five errors keep showing up:
1. Fighting the wrong fear. Half of new lifters worry they will accidentally get bulky; the other half worry they are too old to change at all. Both fears are unfounded. A visibly bulky physique takes years of specialized, deliberate work — it does not sneak up on anyone training twice a week. And the "too old" story collapses the first month you feel stairs get easier. The realistic result of this training is a firmer, more capable body, not a bodybuilder and not a bystander.
2. Cardio only. Walking, cycling, and swimming are excellent for heart and lungs. Keep them. But most cardio loads the skeleton very lightly, and swimming and cycling barely load it at all. You can be impressively fit on a bike and still lose bone on schedule. Strength work is the foundation after 40; cardio layers on top of it, not instead of it.
3. Too heavy, too soon. Enthusiasm plus a 25-year-old memory of your body is a reliable injury recipe. For the first weeks, the correct weight feels almost embarrassingly light, because your real job is learning positions: neutral spine, knees tracking over toes, controlled speed. Technique first makes heavier weight safe later. Weight first makes technique impossible and physiotherapy likely.
4. Quitting at week three. Muscle responds in weeks; bone responds in seasons. People who judge this process at day 20 almost always quit right before it starts compounding. Anchor the sessions to fixed days (Tuesday and Friday beat "sometime this week" every time), keep them short enough to repeat, and let the calendar do what motivation cannot.
5. Training hard, recovering badly. Here is the part people skip: the workout is only the order form. Protein, total nutrition, and sleep do the actual delivery and construction. Train seriously on skipped meals and five hours of sleep and you will collect a fraction of the return. The nutrition section below covers the building materials in detail.
BEFORE THE PROGRAM
If you already have an osteoporosis diagnosis, especially with a previous spine fracture, keep loaded forward bending, heavy twisting, and jumping out of your training until your doctor or physiotherapist clears them — and start under qualified supervision. One rule applies to everyone: muscle fatigue is expected, joint pain is not. Any exercise that produces joint pain gets replaced, not endured.
The Starting Roadmap
Get the green light. A short medical check before you begin is common sense, and it matters most if you have diagnosed low bone density, heart disease, diabetes, high blood pressure, joint or back history, regular medication, or several sedentary years behind you. Your doctor can flag movements to modify and decide whether a bone density scan or blood work makes sense before you load up.
Learn the patterns light. Five movement patterns carry almost everything: squat, hinge, push, pull, and carry. Start each one at a version you can perform slowly and well. If budget allows, three or four sessions with a competent coach at the start will pay for themselves for years — technique learned correctly now is technique you never have to unlearn.
Warm up like it counts. Five to eight minutes is enough: brisk walking or easy cycling, a few mobility movements for hips, shoulders, and ankles, then one very light rehearsal set of your first exercise. Finish sessions with slow walking and gentle stretching while your breathing settles. After 40, this is not ceremony. It is the cheapest injury insurance in the building.
Progress one notch at a time. Keep a simple log of exercise, weight, sets, and reps. When a movement feels comfortable with clean technique, change exactly one variable per week: a couple more reps, one more set, slightly shorter rests, a small weight increase, or a harder variation. Small hinges swing big doors.
Your First Program: Two to Three Sessions a Week
This full-body template is built for complete beginners and returners over 40. Train on non-consecutive days, rest 60 to 90 seconds between sets, and choose effort honestly: most sets should end with two or three clean reps still in reserve. Plan on roughly 45 minutes, warm-up included. All you need is a mat, a sturdy chair, and one light dumbbell.
| Movement | Sets × Reps | Start here | Coaching cue |
|---|---|---|---|
| Bodyweight squat | 3 × 10–15 | Sit down to a chair and stand back up | Chest tall, knees track in line with your toes |
| Stationary lunge, supported | 3 × 8–12 per leg | One hand on a chair or wall for balance | Torso upright, lower slowly, back knee hovers |
| Knee push-up | 3 × 8–12 | Push-ups against a wall or kitchen counter | Straight line from head to knees, ribs down |
| One-arm dumbbell row | 3 × 10–12 per arm | A light dumbbell, around 1–3 kg | Flat back, pull the dumbbell toward your hip |
| Side-lying leg raise | 3 × 12–15 per side | Small, slow range of motion | Toes point forward, hips stay stacked |
| Calf raise | 3 × 15–20 | Both feet, fingertips on a wall | Rise fully, pause, lower under control |
| Plank | 3 × 20–45 seconds | Knees-down plank | Brace hard, never let the lower back sag |
| Superman | 3 × 10–15 | Lift one arm or one leg at a time | Small lift, long spine, one-second hold |
Progress works like this: when every set of an exercise reaches the top of its rep range with clean technique, move one step up next week — a harder variation, a slightly heavier dumbbell, or one extra rep per set. Chair squat becomes full squat becomes goblet squat. Wall push-up becomes knee push-up becomes full push-up. Bone does not respond to motivation. It responds to attendance.
SORENESS OR WARNING?
Normal training soreness is a dull, spread-out ache in the muscle itself. It shows up 12 to 48 hours after the session, affects both sides roughly equally, eases with light movement, and fades within two or three days. Two days after an honest first leg session, sitting down becomes a planned activity. That part is normal, and it is not a membership fee you must pay every week.
Stop and get checked when pain is sharp, stabbing, or pinned to one exact point or joint; when it arrives suddenly during a movement; or when swelling, bruising, clicking, lost range of motion, or pain that worsens after three days enters the picture. Rest is not the opposite of training. It is half of it.
Honest limits, honest timelines
Expect strength to climb fastest in the first month, mostly because your nervous system is learning the movements. Expect stairs, floors, and carries to feel different within two to three months. Expect bone to move on a calendar of seasons and years, with follow-up scans decided by your doctor, not by your impatience.
And keep the roles straight: training works alongside medical care, never instead of it. If your doctor prescribes bone medication, lifting supports that plan; it does not replace it, and no article — this one included — outranks the clinician who knows your history. Responses vary from person to person. Trajectories change before measurements do.
Next, we tighten the safety net: the warning signs that muscle is already slipping away, who needs testing before the loads get serious, and the food rules that supply bone and muscle with building materials.
Warning Signs Your Muscle Is Already Slipping Away
Muscle loss leaves quietly, and it takes small abilities with it first. Read this list slowly and mark what sounds familiar:
- Stairs demand a pause or a handrail that they did not need a few years ago.
- Your grip negotiates with jar lids, heavy bags, and firm handshakes.
- The scale barely moves, but your waistband does.
- Ordinary days — shopping, cleaning, gardening — drain you faster than they should.
- Your lower back or knees grumble with no injury to explain it.
- Balance feels borrowed, and you have already had a near-fall or two.
Two of these deserve a closer look. A stable weight with a growing waist often means muscle is being swapped for fat at the same body weight — a trade that worsens blood-sugar control and steals strength while the scale stays silent. And grip strength is no party trick: clinicians assessing sarcopenia under the revised European consensus known as EWGSOP2 measure exactly the abilities on this list, starting with grip strength and the five-time chair stand.
Try that second one now, before you read another line. Sit in a firm chair, fold your arms across your chest, and stand up five times at an easy pace. Could you finish without pushing off with your hands?
Whatever happened in that chair is information, not a diagnosis. Formal assessment belongs to your clinician. But your answer just told you where your training starts — and muscle keeps its ability to respond to training across your whole life. Treat the wobble as a starting line, not a verdict.
Who Needs Testing Before the Loads Get Serious
Muscle sends home signals. Bone does not, so it gets measured. The standard test is a DXA scan — a quick, painless, low-dose X-ray, usually of the hip and spine — reported as a T-score comparing your bone density with that of a healthy young adult.
Do not confuse the two labels that come back on these reports. A T-score between −1.0 and −2.5 is generally called low bone mass, or osteopenia. At −2.5 or lower, the range is called osteoporosis. A fragility fracture can establish the diagnosis even at a higher score, which is why the number only means something next to your history — and why your doctor, not an article, reads your result.
U.S. screening guidance summarized by the National Institute of Arthritis and Musculoskeletal and Skin Diseases recommends testing for women 65 and older and for younger women with risk factors; for men it makes no blanket recommendation, which makes the risk-factor conversation even more important. Raise the scan question sooner if any of these are yours: a fracture from a minor fall as an adult, a parent who broke a hip, menopause before 45, long courses of steroid medication, a naturally slight build, smoking, heavy drinking, rheumatoid arthritis or similar chronic conditions, or height loss you cannot explain.
This is where the decision changes, because your starting point sets your route:
Diagnosed osteoporosis or a past fragility fracture. You train — with medical partnership, professional supervision at the start, and the guardrails in the next section treated as law, not suggestions.
Low bone mass or several risk factors. Start the beginner program now, and get your baseline, blood work, and follow-up timing agreed with your doctor while strength is already building.
No red flags. You are banking bone and muscle early, from a position of strength. Train consistently and let your doctor set the testing timeline at routine visits.
Training With Fragile Bones: The Guardrails
A diagnosis changes your setup, not your destination. The international Too Fit to Fracture consensus recommends a multicomponent program for people with osteoporosis — resistance training combined with balance training — with exercise selection guided by a qualified professional. Four guardrails put that advice into practice:
Hinge, do not round. Folding at the hips with a long, neutral spine lets glutes and hamstrings carry the load. Rounding the back under weight shifts stress onto the front of the vertebrae — exactly where fragile bone is least forgiving. Learn the hinge light, own it, then load it.
Park loaded bending, twisting, and jumping until cleared. Heavy spinal flexion, twisting under load, and high-impact work stay out of the program for anyone with diagnosed osteoporosis or a previous spine fracture, unless their clinician and coach deliberately bring them back. There is always a substitute movement that trains the same muscle with a kinder spine position.
Train balance little and often. Short, frequent practice beats one heroic weekly attempt. Stand near a counter or sturdy chair, start with still positions such as tandem stance, and progress toward slow, controlled movement only when the still version feels boring.
Feed the posture muscles. The back extensors and glutes hold you tall against the slow forward slump that fragile vertebrae invite. Rows, hip work, and the superman from the beginner program earn their keep here — endurance and position first, load second.
Food First: The Building Materials
Load tells the body what to build. Food decides whether the materials exist. After 40, muscle also answers protein a little less eagerly than it did at 25 — researchers call this anabolic resistance — so both the amount and the spread of protein start to matter more.
Protein: the structural material. The PROT-AGE study group recommends at least 1.0 to 1.2 grams of protein per kilogram of body weight per day for older adults, and more for those who exercise regularly. For a 75-kilogram adult, that means roughly 90 grams a day and upward, spread across meals at about 25 to 30 grams each rather than saved for one evening pile-up. In real-world training, the pattern is usually coffee for breakfast, a polite salad at lunch, then a protein mountain at dinner — move just one protein anchor to breakfast and the whole day changes. A palm-sized portion of fish, chicken, eggs, Greek yogurt, or legumes at each meal gets most people there. Anyone with kidney disease follows their own clinician's protein guidance instead; this target is not for them.
Calcium and vitamin D: mineral and gatekeeper. The NIH reference intakes for calcium sit at 1,000 to 1,200 milligrams a day for adults over 50 depending on sex and age, and the vitamin D reference range runs from 600 IU a day up to age 70 to 800 IU a day after 70. Dairy, sardines eaten with their bones, leafy greens, and fortified foods cover calcium for most people who eat them regularly. Vitamin D is harder to eat your way to: sensible sunlight and fatty fish help, aging skin produces less of it, and only a blood test tells you where you actually stand. Test, do not guess. And respect the ceiling — NIH sets the calcium upper limit at 2,000 milligrams a day for adults over 50, and chronic overshoot, almost always from supplements rather than food, is associated with kidney stones.
The supporting cast. Vegetables, fruit, legumes, nuts, and whole grains quietly deliver potassium, magnesium, vitamin K, vitamin C, and the fiber that steadies blood sugar between meals. One plate rule covers most of it: vegetables on half the plate, protein you can point to, and whole grains over refined ones. Drink water across the day and around sessions; pale-yellow urine is the simplest gauge that you are keeping up.
Supplements: gap-fillers, not foundations. The honest order is test, then food, then a supplement chosen with your clinician to close a measured gap. Bring your full list to medical appointments, because common supplements interact with prescription medicines. Protein powder is simply convenient food for days when appetite or schedule falls short. Creatine is among the most studied supplements in training research and gets asked about often; it is optional, it is not a steroid, and like everything in this paragraph it belongs in a conversation with your doctor — especially with any kidney history — rather than in a shopping cart on impulse.
You now have the program, the guardrails, and the grocery list. What remains is the part that decides whether any of it survives contact with real life: staying consistent for years, reading your progress honestly, and getting straight answers to the questions everyone over 40 asks before they start.
Making It Stick: Strength as a Way of Life After 40
Programs rarely fail in the gym. They fail on calendars. Life after 40 runs full — careers, children, aging parents — so the winning program is the one designed around your actual week, not the week you wish you had. Two or three focused sessions will outlast any heroic plan that needs perfect conditions.
Start at home, upgrade later. A chair, a mat, a band, and one pair of light dumbbells cover the entire beginner program. Buy equipment after the habit exists, not as a down payment on motivation. Twenty honest minutes in the living room beat a gym membership you visit twice.
Use exercise snacks. Short bouts sprinkled through the day add up: calf raises while the kettle boils, chair stands during TV ads, stairs taken on purpose, shopping carried instead of carted the last stretch. Bone and muscle register total weekly effort, not just official workouts.
Schedule it like an appointment. Block the sessions in your calendar, lay out clothes the night before, and decide once instead of renegotiating every morning. Friction kills more programs than weakness ever will.
Train with someone. A spouse, a friend, a small class — another person expecting you changes the math on low-energy days. Shared sessions also make form checks and loaded carries safer and more enjoyable.
Track function, celebrate function. Log your weights and reps, and once a month test one simple marker, such as how many chair stands you complete in 30 seconds or whether the stairs still need a handrail. The scale is the weakest judge here: weight can hold steady while muscle quietly replaces fat. And write your reason for starting where mornings happen — the mirror, the fridge, the phone. Purpose outlasts mood.
QUICK SAFETY CARD
- Diagnosed bone loss or a past fracture: clearance and supervision come before heavier loads.
- Joint pain means stop and swap the exercise. Sharp pain means stop the session.
- Chest pain, severe breathlessness, dizziness, or faintness: stop and seek medical care promptly.
- Loaded bending, twisting, and jumping stay parked until your clinician clears them.
- New diagnosis or new medication: update your coach and check with your doctor before progressing.
- When in doubt, go lighter and ask. Pride heals slower than muscle.
Your First Week, Step by Step
- Book the doctor visit. Ask whether a DXA scan and a vitamin D blood test make sense for your risk profile.
- Put two or three 45-minute sessions into this week's calendar, on non-consecutive days.
- Run the beginner program with body weight only for the first two weeks. Film one set per exercise if you can; technique is the whole assignment.
- Set your protein floor: body weight in kilograms multiplied by 1.2 gives your minimum daily grams to aim for, spread across meals. Anchor protein at breakfast first.
- Add one calcium-rich food to your daily routine and a short, sensible sunlight break on most days.
- Recruit accountability: a training partner, or two or three starter sessions with a qualified coach.
- Write your why on one line of paper and place it where you will see it every morning.
Frequently Asked Questions
Is it too late to start resistance training after 40?
No. Muscle keeps responding to training in your fifties, sixties, and seventies, and most research on older beginners starts exactly where you are. What changes with age is the on-ramp: lighter loads, cleaner technique, and patience with progression. The best time to start was years ago. The second-best time is this week.
Can I lift weights if I've already been diagnosed with osteoporosis?
Usually yes, and structured strength training is part of standard osteoporosis care. The conditions are medical clearance, a supervised start, and strict guardrails: neutral-spine lifting, no loaded forward bending or heavy twisting until cleared, and steady balance work. Your doctor and coach set the starting loads together, and progress stays gradual.
Will resistance training make me bulky?
Almost certainly not. A bulky physique takes years of deliberate, specialized training and eating aimed at size. Training two or three times a week with the approach in this guide produces firmer muscle, better posture, and a more capable body. Most people over 40 look more athletic, not bigger.
Which exercises are best for bone density?
The patterns that load the hips and spine through large muscles: squats, hip hinges, presses, rows, lunges, and loaded carries. They deliver the mechanical signal bone responds to, and they train the movements daily life depends on. Weight-bearing activity such as brisk walking and stairs supports the same goal between sessions.
How many times a week should I train?
Two or three full-body sessions a week on non-consecutive days is the sweet spot for beginners, with at least one rest day between sessions. Add a session later only if recovery stays solid. Consistency across months and years matters far more than squeezing extra workouts into one ambitious week.
Are yoga and Pilates enough to prevent osteoporosis?
They are excellent for mobility, balance, breathing, and core control, and they pair well with lifting. On their own, though, they rarely provide progressive loading strong enough to be your entire bone strategy. Keep resistance training as the base for bone and muscle, and let yoga or Pilates support it.
Should I feel sore after every workout?
No. Mild, dull muscle soreness a day or two after training is common early on and usually harmless. Sharp pain, joint pain, swelling, or soreness that worsens after three days is a different signal: stop that exercise and get it checked. Soreness is a side effect, never the goal.
How heavy should the weights be?
Heavy enough that the last couple of reps feel genuinely challenging while your technique stays clean, with about two or three good reps left in reserve. Start lighter than your ego wants, learn the positions, then add small amounts of weight as the movement becomes comfortable.
Can I combine resistance training with cardio?
Yes, and the combination serves heart, muscle, and bone better than either one alone. Separate days work well. If both land in the same session, lift first while you are fresh so technique and load quality stay high, then finish with cardio.
When will I see results?
Energy, sleep, and everyday strength often improve within the first few weeks. Visible muscle change and bigger strength jumps usually take two to three months. Bone moves slowest: allow many months, and let your doctor schedule any follow-up scans. The results that protect your independence come from staying the course for years.
Start Where You Stand
Look, aging is not optional. How much strength you carry into it largely is. After 40, muscle and bone leave on a schedule — but they answer to load, protein, sleep, and repetition. You now know the mechanism, the beginner program, the guardrails, and the grocery list. Nothing here requires talent, youth, or a perfect week. It requires attendance.
So tell me: at 70, what do you still want to lift, carry, climb, and do without asking anyone for help?
Whatever you just pictured is the real target of every set in this guide. Start light this week. Keep the appointments. Let the quiet months compound. The strongest version of your next decade is built one ordinary session at a time.
Stay strong,
