Part of Strength training for older adults
Strength training for seniors over 70: what actually changes
Warning signs, and when to get help
What changes after 70, and what does not
The training does not change in kind. A leg gets stronger at 78 the same way it got stronger at 48: you load it, you let it recover, you make it a bit harder, and you keep going. Anyone who tells you there is a separate science for people over 70 is usually selling something.
What changes is everything around the training. People arrive at this age with a list rather than a blank page: another condition or two, a set of medicines, an operated knee, a shoulder that has never been right, a winter in which they stopped and never quite started again. The margin is thinner too. Two weeks in bed with a chest infection at 45 costs you a fortnight. At 82 it can cost you the ability to get off a low sofa, and winning that back takes months.
One physical thing does genuinely change, and it is worth knowing because it explains a common complaint. Muscle power, which means strength used quickly, declines earlier and more steeply with age than strength measured slowly does (Reid and Fielding 2012). That is why someone can still push up out of a chair when they take their time over it, and cannot do it fast enough to catch themselves when they trip. Speed is trainable, and our strength program for older adults handles it without a gym, by asking you to come up out of the chair a little faster once the slow version is solid, not by adding weight.
The question of whether it is too late is answered in short form in the FAQ on strength and balance exercises for seniors, and the answer is no. The rest of this page is about what to expect and what to watch, not about whether to start.
Can you build muscle after 70?
Muscle still responds to training in your seventies and eighties. That is not an encouraging guess, it is what the trials found, and the next section gives them. What differs from a younger body is the starting point, how much of the first few weeks goes on learning the movements, and how much a chest infection or a fortnight of pain costs you along the way.
Two practical things decide how much you get. The first is whether the work gets harder over time. A program that never changes stops producing much, and the commonest reason an older adult tells us the exercises did nothing is that they are still doing their first week, two years later. The second is food, and this page gives you no figure for it, because that answer is yours rather than general. Our strength program for older adults carries the longer version of it.
The NHS notes that people aged 65 and over are particularly at risk of malnutrition. How much protein and energy you need depends on you and your health, so discuss it with your GP or a dietitian. If you are losing weight without trying, see the warning signs below.
Size is not the measure worth watching anyway. In both the trials in the next section, strength rose far more than the muscle itself did, and what strength is for is whether you can get off a chair without your hands. The parent page sets out what progress looks like before it shows up in a weight, which is the section to read before you start looking in the mirror.
What the trials in this age group found
Most writing on this subject quotes trials in people in their sixties and lets the reader assume it applies at 85. Two older studies went straight to the oldest and frailest, and they are still the clearest answer we have.
In the first, ten nursing home residents with an average age of 90 did eight weeks of high-intensity strength training for the legs. Nine finished. Leg strength rose by an average of around 174%, the muscle area in the middle of the thigh by about 9%, and the speed of a heel-to-toe walk by around 48%, in people up to 96 years of age (Fiatarone 1990). The percentages look extraordinary because the starting point was so low, and it was a very small group, so read the direction and not the size of the figures.
The second was bigger and better controlled. One hundred frail nursing home residents, average age 87, were put into four groups for ten weeks: strength training, a nutritional supplement, both, or neither. Muscle strength rose by an average of 113% in the residents who trained, against almost no change in those who did not. Walking speed and stair-climbing power went up as well, by much smaller margins, around 12% and around 28%, and so did how much the residents moved about of their own accord. The supplement on its own improved none of the main outcomes (Fiatarone 1994).
Two cautions go with those trials. The training was supervised closely, in an institution, with staff present, which is not what a reader doing this alone in a kitchen has. And the participants were frail and very inactive, so the scale of the gains says more about how far they had fallen than about what anyone can expect. Read them as proof that the machinery still works, which is what the question is really asking.
Is it safe to lift weights at 70 or 80?
For most people, yes, with the program built for them and the technique taught properly rather than guessed. The WHO guidelines put the general position like this: activity is considered safe for adults living with the chronic conditions they reviewed where nothing specific rules it out, and the benefits generally outweigh the risks (Bull 2020). The UK osteoporosis consensus says the same thing for the group most often warned off, and recommends muscle strengthening rather than avoiding it (Brooke-Wavell 2022).
The exceptions are specific and they are about what you have, not how old you are. Our page on exercises seniors should avoid works through each of them one by one, and the last section here lists who should ask before they start.
What does change with age is how little margin there is for a bad decision about load. A joint pushed too hard at 35 complains for a week. The same mistake at 80 can take a month out of the program and the confidence with it. So the useful caution is not do less, it is go up in smaller steps than you think you need to, and judge each step by the next day.
Starting light is right. Staying light is the mistake
Almost everyone starts too light, which is correct. A first session should teach the movement, not test you. Where it goes wrong is six months later, when the same band and the same chair are still in use and the reader has concluded that strength training does not work for them.
Progress at home is mostly about taking help away rather than adding weight, and that order is worth understanding before you try to speed it up. Our guide to how a physical therapist progresses an exercise explains it, and the parent program gives the actual sequence for each exercise, from sit to stand with the armrests through to the chair squat off a lower seat. The arm work moves the same way, from wall push ups and the seated row with a band to a firmer band and then a weight.
Two home measurements beat a mirror, and both have their own pages with their own limits: the 30-second chair stand test and the grip strength test at home. Take the numbers to a clinician instead of scoring yourself with them.
More conditions, more medicines, slower recovery
Three things crowd into the same program at this age, and each has a different owner.
Other conditions. Having a heart condition, diabetes, arthritis or a lung condition is a reason to have the program set properly, not a reason to skip it. The conditions the WHO reviewed for that safety statement were cancer, high blood pressure, type 2 diabetes and HIV (Bull 2020), so it covers part of that list and not all of it. For everything else, a diagnosis decides how the program is built, not whether you get one. Where a joint rather than your strength is the thing that limits you, the gentler seated and standing exercises for older adults set is written for a painful hip, and the osteoporosis program covers thin bones.
Medicines. Some of them leave people unsteady, particularly on standing, and the World Falls Guidelines recommend that reviewing medicines and withdrawing the ones that increase falls risk should be part of falls prevention (Montero-Odasso 2022). That review is a conversation with your own doctor or pharmacist, never a change you make yourself, and it is worth asking for by name if you have felt woozy standing up.
Recovery. This is the part most people get wrong by ignoring it, and the fix is already built into our program: you move up a stage when the current one feels easy and you have recovered by the next day. Soreness for a day or two after something new is ordinary. A joint that is more painful or more swollen the next day means the load was too much for now, so do less next time rather than stopping. If sitting down to a session is what never happens, exercise snacks makes the case for doing it a minute at a time through the day.
Strength training for seniors over 70 at home, or in a class
At home is where nearly all of this gets done, and the early stages of our program need a firm chair, a wall and a band rather than a gym. What home cannot give you is somebody watching the first attempt, which is why a single physio appointment to set your stage is the best value in this whole subject.
If you have fallen in the past year, feel unsteady on your feet, or take medicines that make you dizzy, keep a hand on a kitchen counter or the back of a sturdy chair for the whole of the standing exercises, practice only when someone else is at home, and ask your doctor or physio about a falls check.
If you live alone, that rule still stands, so plan around it rather than ignoring it. Do the exercises that ask for someone to be at home at your physio appointments or in a class instead, keep to the seated and supported work when you are on your own, and ask your physio which of the standing exercises you may do alone. Keep your phone in a pocket rather than in another room, so you can reach it from the floor, and ask about an alarm you wear.
A class adds the two things a kitchen cannot: somebody to correct you, and a reason to turn up in February. The FAQ below has the questions worth asking before you pay for one.
Strength is only half of the job at this age. The other half is balance, which trains differently and is not covered by lifting, and balance and falls prevention holds that program. Readers taking a weight loss medicine have their own page, because the sums change: older adults on GLP-1 medicines.
How long before you notice anything?
Sooner than most people expect for strength, and later than most people want for anything visible. The two trials above measured their gains over eight and ten weeks of supervised training (Fiatarone 1990, Fiatarone 1994), and that is a fair guide to the order of things, with the caution that those programs were run for people by staff rather than by the people themselves.
What you notice first is usually not a number. It is that you stopped pushing off the arms of the chair, or that the stairs no longer need a plan, or that the shopping comes in from the car in one trip. The parent program has a section on exactly that, and it is the one to read in week three when nothing seems to be happening.
Here is the part nobody enjoys hearing. This is not a course you finish. What we see in clinic is that strength does not stay bought: people who stop come back weaker than they left, and at 80 that costs more than it did at 40. So the version that works is the one you will still be doing next year, done at an intensity that is honestly hard, rather than the ambitious one you will abandon in March.
Who should check with a doctor or physio first
With a heart condition or high blood pressure, check with your doctor before you start. This matters most if your blood pressure is not under control. If you have high blood pressure, breathe steadily through every repetition and never hold your breath. The NHS asks anyone who has not exercised for a while, or who has medical conditions or concerns, to speak to a GP before they start.
If you have had an operation recently, or have broken a bone that is still healing, follow the program from your surgeon, fracture clinic or physio rather than this one. A healing bone has its own timetable for how much weight and load it can take, and that timetable comes from the team looking after it rather than from how the arm or leg feels.
A repair runs to its own clock in the same way. Where a tendon, a ligament or a muscle has been stitched back together, it can feel comfortable long before it can take load, so the limits your surgical team set on lifting, pushing, reaching and leaning on the arm hold until that team lifts them, whatever the limb feels able to do.
If you have had a hip or knee replacement, or a broken hip fixed with screws, a nail or a plate, or with part or all of the hip replaced, get the go-ahead from your surgeon or physio before you try the sit to stand exercises, the chair squat, standing hip abduction, stair climbing, step ups, the supported lunge or getting up from the floor. Some operations limit this kind of work for the first months, so the timing depends on your surgery. After a broken hip, hip fracture rehab is the program to follow instead of this one.
The UK guidelines suggest that for people with frailty, moderate to severe dementia, past fractures of the spine or regular falls, new exercises may be better supervised by a trained professional at first. A physio or a falls service can help with this.
While you exercise, stop straight away if you have any of these: chest pain or pressure, dizziness or feeling faint, a racing or irregular heartbeat, or being far more out of breath than the effort should cause. What to do next is in the warning signs below.
If chest pain, pressure or tightness does not ease quickly when you rest, spreads to your arm, neck, jaw, stomach or back, or comes with sweating, feeling sick, feeling light-headed or being short of breath, call emergency services straight away, as this can be a heart attack. If it eases quickly and none of these happen, get medical advice the same day, and do not exercise again until you have been checked.
None of the above is a reason to sit still while you wait for an appointment. Standing up out of a chair is something almost everyone can start today, and the staged strength program for older adults begins there.

Warning signs
Get emergency help now
- Emergency: if chest pain, pressure or tightness does not ease quickly when you rest, spreads to your arm, neck, jaw, stomach or back, or comes with sweating, feeling sick, feeling light-headed or being short of breath, call emergency services straight away, as this can be a heart attack. If it eases quickly and none of these happen, get medical advice the same day, and do not exercise again until you have been checked.
- Emergency: any sign of a stroke, even if it goes away. That means a face that droops on one side, an arm you cannot lift or keep up, slurred or muddled speech, weakness or numbness on one side of your body or face, sudden blurred vision, double vision or loss of sight, trouble swallowing, sudden dizziness with unsteadiness or falling over, a sudden severe headache, or a sudden fall where your legs give way but you do not black out (a drop attack). Call emergency services straight away.
- Emergency: a racing, pounding, fluttering or irregular heartbeat that does not settle when you rest, or that comes with dizziness, feeling faint or fainting, chest pain or shortness of breath. Call emergency services straight away. If it has already stopped, get medical advice the same day.
- Emergency: you have just fallen and cannot get up, or you think you may have hurt your head, neck, back or hip. Stay where you are, keep warm and call emergency services, or get someone to call for you. If you got up and walked without trouble and only notice pain later, use the same-day lines in this list instead.
- Emergency: you fell and cannot remember the fall or how it happened. Go to an emergency department straight away, and do not drive yourself. You may have blacked out or hit your head without knowing it.
- Emergency: you have had a fall or an injury and now have severe hip pain, or you cannot walk or put weight on the leg. Call emergency services or go to an emergency department. This can be a sign of a broken hip (hip fracture).
- Emergency: you have had a hip replacement and have sudden severe pain in your hip or groin, sometimes with a clunk or pop, and you cannot move the leg or put weight on it, or the leg suddenly looks shorter or turned in or out. Do not try to walk on it or push it back into place. Keep still and call emergency services or go to an emergency department, and do not drive yourself. Your new hip may have come out of its socket (dislocated), and a medical team needs to put it back.
Get help today
- Same day: you blacked out or fainted, even for a moment. Get medical advice the same day. Call emergency services instead if the person is not breathing, cannot be woken within 1 minute, has not fully recovered or has trouble speaking or moving, has chest pain or a pounding, fluttering or irregular heartbeat, fainted while exercising or lying down, is shaking or jerking, or was badly hurt.
- Same day: dizziness, lightheadedness, blurred vision or feeling faint when you stand up that is new for you, does not pass within a minute or two, keeps happening, or has made you fall. Sit or lie down, and get medical advice the same day. This can be a drop in blood pressure on standing (postural hypotension), a type of low blood pressure, which the NHS lists among the causes of falls, and your doctor can check it. Tell them about your medicines, because some can cause it. If it does not settle within a few minutes of sitting or lying still, call emergency services. If you faint, use the fainting line above.
- Same day: dizziness or feeling faint during or after exercise, other than the brief lightheadedness as you stand up covered in the line above, without any of the emergency signs above. Stop the exercises and get medical advice the same day. If you faint, it does not settle within a few minutes of sitting still, or you cannot stand or walk steadily, call emergency services.
- Same day: after a fall, you are in pain, have hurt yourself or feel unwell, or you were on the floor for an hour or more, without any of the emergency signs above. Get medical advice the same day, even if you managed to get up.
- Same day: a calf or thigh that is newly swollen or getting more swollen, warm, tender, red or darker than usual, has swollen veins that are sore to touch, or has a throbbing or cramping pain that does not fit your injury or condition, or that feels different from normal muscle soreness after exercise. This can be a sign of a blood clot (deep vein thrombosis), especially after surgery, an injury, time in a cast or boot, a long trip or a spell of being much less mobile than usual. Get medical advice the same day. If you are also short of breath or have chest pain, call emergency services.
- Same day: new hip or groin pain after a fall, even a small one, if you are older, have low bone density (osteoporosis) or have taken steroid tablets for a long time, even if you can still walk. Get medical advice the same day. A broken hip is not always obvious at first.
- Same day: since an operation, the wound is red, hot, swollen, leaking fluid or opening up, you have a fever or feel hot and shivery, or the pain in that area is new or getting worse quickly. Contact your surgical team or the ward you went home from the same day rather than waiting for your physio appointment, and if you cannot reach them, go to an emergency department the same day. This can be an infection in the wound or deeper, around a repair or a new joint.
- Same day: you have had a hip replacement and, after a fall or a knock, even a small one, your hip, groin or thigh is newly painful, bruised or swollen, even if you can still walk and your leg looks normal. Stop the exercises, go back to your crutches or frame and keep your full weight off that leg, and contact your surgical team or get medical advice the same day. A break in the bone around a new hip is not always obvious at first, and walking normally on one can move the broken ends apart.
- Same day: you have had a hip replacement and your hip clunks and feels as if it partly slipped out of place and went back, even if it settles straight away and your leg looks normal. Stop the exercises, avoid the movement that brought it on, go back to your crutches or frame, and keep away from deep bending, crossing your legs and twisting on that leg until you have been seen. Contact your surgical team or get medical advice the same day. If the leg then looks shorter or turned, or you cannot move it or put weight on it, call emergency services.
- Same day: back pain after a minor fall or strain if you are older, have low bone density (osteoporosis) or have taken steroid tablets for a long time. Get medical advice the same day. Until it has been checked, stop the exercises and keep away from lifting, bending forward and twisting, because those load a bone in the spine that may be broken.
- Losing weight without trying. If you are being treated for cancer now, contact your cancer team the same day.
- Losing weight without trying. If you also have new back or neck pain, get medical advice the same day.
Book an appointment
- A new fall, even if you were not hurt. If none of the lines above apply, book an appointment with your doctor within a few days and tell your physio before your next session. A doctor can check for causes such as muscle weakness, weak bones or eyesight problems, and may refer you to a falls service.
- Losing weight without trying. See your doctor within a day or two and mention it.
Common questions
Can you build muscle at 80?
Yes. The trials that answered this question were done in nursing home residents in their late eighties and nineties, not in fit sixty-somethings, and the section above on what those trials found gives the figures and their limits (Fiatarone 1990, Fiatarone 1994). What is different at 80 is not whether muscle responds to training. It is that the margin for a setback is smaller, so where you start and what you hold on to matter more than how ambitious the plan is. Start where our strength program for older adults starts, which is seated or with the chair arms taking some of your weight, and get a physio to set your stage if you can. If you have had a hip or knee replacement, or a broken hip fixed with screws, a nail or a plate, or with part or all of the hip replaced, get the go-ahead from your surgeon or physio first, because some operations limit this kind of work for the first months and the timing depends on your surgery.
Should seniors lift heavy weights?
The honest answer is that heavy is a relative word and the useful version of this question is for your clinician rather than for a web page. What the evidence in the oldest age bands shows is that the training which produced the large gains was closely supervised and genuinely effortful, not gentle (Fiatarone 1990, Fiatarone 1994). What it does not show is a weight that is right for you, which depends on your joints, your heart, your blood pressure, your bones and what you have had operated on. The section for clinicians on our strength program for older adults carries the loading framework physios work from, and it is a starting point to be adjusted rather than a prescription. Two things are not negotiable whatever the weight: if you have high blood pressure, breathe steadily through every repetition and never hold your breath, and with a heart condition or high blood pressure, check with your doctor before you start.
How many times a week should seniors lift weights?
There is a published answer to this and it is not ours to invent, so we keep it in one place. The WHO and the UK Chief Medical Officers both set a floor for muscle strengthening in older adults, and the NHS puts it alongside balance and flexibility work. Our strength program for older adults carries those numbers with the guideline each one comes from, and strength and balance exercises for seniors carries the falls side, where the World Falls Guidelines ask for more than most people expect (Montero-Odasso 2022). Read them there rather than from a number here. In practice most people over 70 do better with short sessions spread through the week than with two long ones, and your physio will adjust this.
What should I look for in a class or a trainer?
Four questions sort the good ones from the rest, and you can ask all of them on the phone. Will somebody set my starting level rather than putting me in with everybody else. Does the work get harder over the weeks, or does the same session repeat forever. What do you want to know about my health and my operations before I come. And is there something to hold on to for the standing work. A class that cannot answer the first and the third is the wrong class, whatever it is called. If you have had an operation in the past months, take the sheet your surgical team gave you with you and hand it over, because the instructor cannot guess what was restricted.
