Strength training in your 70s: how often and how heavy

Maybe your doctor said "do some weights". Maybe a bone scan came back thin, or a friend had a fall and it shook you. Either way, you're in your 70s, you've heard that strength training matters, and nobody has told you what it looks like on an ordinary Tuesday: how often, how heavy, and whether it's safe.

This page is written for someone starting from zero with a kitchen chair and maybe a pair of light dumbbells. It works just as well if you're reading on behalf of a parent.

And if your first question is whether muscle still grows this late: it does, even in your 90s. The frailty studies are worth a read if you need convincing.

Do you need a doctor's OK first?

Probably not, if you start light and build up. The World Health Organization's guidance says that if you have no medical reason to avoid it, you generally don't need a doctor's clearance to start light or moderate activity, the kind that's no harder than a brisk walk.¹

The standard way to find out whether you're an exception is the PAR-Q+, a free one-page questionnaire that trainers and clinicians use. It takes about a minute. In our words, it asks whether:

• a doctor has told you that you have a heart condition or high blood pressure
• you get chest pain at rest, during daily life or when you're active
• you've lost your balance from dizziness, or blacked out, in the past year
• you have another long-term condition, or take medicine for one
• a bone, joint or muscle problem from the past year could get worse with activity
• a doctor has told you to exercise only under medical supervision

Fill in the real form rather than relying on our summary. If every answer is no, start slowly and build up. If any answer is yes, the form walks you through a few follow-up questions, and a conversation with your doctor or physio is worth having. The form also says to hold off starting while you have a passing illness like a cold or a fever.

Go in with a better question than "am I allowed?" Ask "which movements should I change, and is there anything I should avoid?" For most people, that conversation is about how to start, not whether to.

Once you're training, a few signs mean stop the session and get checked straight away: dizziness, being far more out of breath than the effort deserves, chest pain or pressure, or a racing or fluttering heartbeat. Don't train again until you've been cleared.² Tired muscles, and a little soreness the next day, aren't on that list.

How often: is once a week enough?

It's a real start. One of the few trials to test this directly took people aged 65 to 79 and gave them the same workout once, twice or three times a week for six months. All three groups got much stronger, and by about the same amount.³

• No training: 4%
• Once a week: 37%
• Twice a week: 42%
• Three times a week: 40%

Taaffe and colleagues, 1999

There's a catch. Those sessions were hard: three sets of eight reps at a weight close to the most each person could manage for eight. They were also supervised, and the groups were small. A later, shorter trial pointed toward two days for everyday jobs: of the groups it tested, only the one lifting heavy twice a week clearly got better at standing up from a chair.⁴

So here's how it adds up:

• Twice a week is the target. It's what the CDC and WHO¹ recommend for everyone over 65, working the legs, hips, back, belly, chest, shoulders and arms.⁵
• Once a week is worth doing when that's all your life allows, as long as the sets are genuinely effortful.
• A third day doesn't seem to add much strength. Spend that time on walking and balance instead. The week further down shows how.
• Leave a day between sessions that work the same muscles.⁶ Why recovery matters more with age is its own story, told in training in your 50s.

Your first sessions

Before the first one, take a two-minute test so you have something to beat: the 30-second chair stand. Use a sturdy chair without arms, pushed against a wall. Cross your arms on your chest and count how many times you can stand all the way up in 30 seconds. Have someone nearby the first time.

The CDC counts fewer than 12 stands for men or 10 for women as below average at ages 70 to 74, and fewer than 11 or 10 at 75 to 79. If you need your hands to get up, the score is zero for now.⁷ None of that is a verdict. It's where you start, and it's the number you'll watch go up. Write it down with the date.

For the first week or two, use no weights at all, or a filled water bottle. You're learning the moves, and a chair, a wall and a kitchen counter are enough for most of them.

After that, the numbers are simple. Your target is 10 reps a set. Start each move with a weight you could lift about 15 times if you pushed, and do 10. That will feel easy, and it's meant to: it's our rule of thumb for the light-to-moderate start the American Heart Association recommends for beginners.² The rule in "When to add weight" below then moves you up, quickly at first, until the last rep or two of each set of 10 is genuinely tough. That effort, not the number on the dumbbell, is what makes you stronger.⁶

You won't find a starting weight in pounds here, on purpose. At 70 the right one runs from a water bottle to more than you'd guess, and a number that's wrong for you does more harm than none. If you're buying dumbbells, try a few sizes in the shop with the 15-rep test, or get one adjustable dumbbell with small plates ("When to add weight" shows why). How much weight to start lifting with goes into that first choice in more detail.

Here's the whole session. Go through the moves in order, resting about a minute between them. That's one round, and one round is enough at first. After two or three weeks, add a second round, which may work a little better.⁶ Breathe out as you push or lift, and don't hold your breath.

1. Warm up for five minutes

   March on the spot, walk around the house, roll your shoulders. You're done when you feel warm, not tired.

2. Sit to stand: 10

   Push a sturdy chair against a wall. Stand all the way up, then sit down slowly. Use your hands on your knees if you need them. Harder later: no hands, a slower sit, then a dumbbell held at your chest.

3. Counter push-up: 10

   Hands on the edge of the kitchen counter, body in a straight line. Lower your chest toward the counter and push away. Too hard? Use the wall. Harder later: a lower surface, like a sturdy table.

4. One-arm row: 10 each side

   One hand on the back of a chair, a dumbbell (or a bag with a few tins in it) in the other. Pull your elbow back toward your hip, then lower.

5. Step-up on the bottom stair: 10 each leg

   Hold the rail. Step up, bring the other foot up, step back down. Do all your reps leading with one leg, then switch. Harder later: a dumbbell or a bag in your free hand.

6. Calf raises at the counter: 10

   Fingertips on the counter, rise onto your toes, lower slowly. Harder later: one foot at a time.

7. Carry two shopping bags: about 30 seconds

   Load them evenly and walk the hallway, standing tall. It trains your grip and your trunk in one go. Harder later: heavier bags.

8. Stand on one foot: up to 30 seconds each side

   Next to the counter, fingertips touching it if you need to. Harder later: hands hovering just above it.

There's nothing magic about these eight. They cover the jobs that matter most at this age: standing up, pushing, pulling, climbing, carrying and balancing. Swap any of them for something that suits your joints better.

One more skill worth practising: getting up off the floor. If you ever do fall, getting yourself back up is what matters next, and it can be practised like any other move. Once sit-to-stands feel steady, try it at the end of one session a week, with a sturdy chair beside you and someone else at home. If kneeling hurts, skip it and ask a physio for a version that suits your knees.

1. Kneel on a cushion, both hands on the chair seat

2. Bring one foot forward, flat on the floor

3. Push up through that front leg

   Lean on the chair as much as you need.

4. Turn and sit on the chair

   Going back down to the floor is the same in reverse.

The first few weeks are when habits form, good and bad, so it helps to have someone watch a few reps. A family member filming you on a phone works, and what a coach looks for tells them what to watch. A coach watching live is the other way, and it's what we do.

What a week looks like

Here's one way to fit it all together. The days are only an example, so move them to suit your week.

The five walks add up to the 150 minutes a week the guidelines pair with strength work.⁵ Brisk means you can talk but couldn't sing the words of a song.⁸ Balance turns up four times, in the spirit of WHO's advice that over-65s mix balance and strength work on three or more days a week.¹ On a week when you can only manage one strength session, keep Tuesday and keep the walks.

When to add weight

The American Heart Association's guidance has a tidy rule for this, sometimes called "2 for 2". Your target is 10, so the signal is 12. Whenever a set of 10 feels easy, carry on and see if you get to 12 in good form. When every set of an exercise reaches 12, two sessions in a row, the weight can go up by 2 to 10 percent.²

Here's how it plays out at home. Say you're rowing two sets of 10 with an 8 lb dumbbell. On Tuesday, both sets get to 12. On Friday, same again. That's your signal. With your easy starting weights you'll hit it most weeks at first. That's the rule doing its job, and it slows down by itself once 10 reps start to feel hard.

The snag is that fixed home dumbbells don't come in 8.5 lb. The next one up is usually 10 lb, which is a 25 percent jump. An adjustable dumbbell with small plates, like the one in the photo, gets around that. Otherwise, when you move up, drop the reps: do two sets of 7 or 8 with the new weight and build back up over the next few weeks until the rule says go again. If even that's too much, stay at 8 lb and make it harder in other ways, like a slower lowering, a pause at the top or an extra set. Progressive overload at home has more of those.

Most of the session uses no dumbbell at all, and the same signal works there: switch to the "harder later" version in that move's step and drop back to 10. For the carry and the one-foot stand, which are timed, move on once the full 30 seconds feels easy.

Your worries, answered

"I'll hurt myself." Serious problems are rare in the trials of older lifters, and none were put down to the exercise itself. Aches are common, though: sore muscles and achy joints turned up in many of them.⁹ Mild soreness for a day or two is normal. A joint that still aches at your next session is a sign to go lighter, shorten the movement or swap the exercise, not to push through.

"I'm worried about falling." Then train balance as well as strength. In the main review of falls in older people living at home, programs that mixed balance and strength probably cut falls by about a third, and balance-focused programs by about a quarter. Strength training on its own hasn't been shown to cut falls.¹⁰ That's why the one-foot stand is in every session, and twice more in the week above. Balance practice has harder versions for when it gets easy, and training in your 60s explains why moving with a bit of speed matters for catching a stumble.

"I have osteoporosis." Bone experts recommend strength and balance training for people with osteoporosis, including after a spinal fracture, rather than relying on walking alone. They're also honest that nobody has measured the risks precisely.¹¹ Ask your doctor or physio which movements suit your spine, and train the rest.

"My blood pressure is high." If it's controlled, light-to-moderate strength training is considered safe, as long as you keep breathing through each rep. If you take blood-pressure medicine, finish with a longer, easier cool-down so you don't feel light-headed when you stop.² If it's high and not controlled, or you don't know your numbers, get it checked first. That's exactly what the PAR-Q+ asks about.

"I have arthritis." The trials behind the "I'll hurt myself" answer also found that strength training eased osteoarthritis pain.⁹ Keep the reps slow and stay in a range of motion that feels comfortable. If a move hurts the joint itself, rather than working the muscle around it, swap it.

"I've had a hip or knee replaced." Your surgeon and physio know your implant, so ask them which positions to avoid and for how long, then train everything else. Lifting weights after knee or hip replacement covers when to start and how to build up.

What to expect, and when

1. Weeks 1 to 3

   Steadier, not yet stronger

   The moves stop feeling wobbly and you stop having to think about them. Much of this early progress is thought to be your nervous system getting better at using the muscle you already have.¹² Around week three, add the second round.

2. Months 2 to 3

   The numbers move

   A few of your weights or moves have gone up a step under the 2 for 2 rule. Retest the chair stand and write the new count next to the first one.

3. Month 6

   Real strength

   This is the point where the gains in the chart above were measured. You'll notice it more on the stairs, getting out of the car and carrying the shopping in than in the mirror.

One thing outside the sessions changes how much you get from them: protein. Older muscle seems to need a bigger helping at a meal to get the same building out of it. In one analysis comparing men in their early 70s with men in their early 20s, the older men seemed to need more protein per meal.¹³ How much protein you need after 40 works out your number in grams, with a day of ordinary food that reaches it.

One fair warning: your medicines, joints and history shape what's sensible far more than the year you were born, so treat every number on this page as a direction, not a promise.

When life gets in the way

Grandchildren come to stay, a knee flares up, a winter bug flattens you for a week. That's normal, and it costs less than you'd fear. What predicts strength gains best isn't the exact sets or weights. It's how long you keep at it.¹⁴ The plan you're still doing in March beats the perfect one you dropped in two weeks. And strength you've built holds up well through months of much lighter training, even when muscle size slips.¹⁵ So easing back through a busy stretch is unlikely to cost you much.

What does cost you is stopping moving altogether. Healthy people around 67 who spent ten days in bed lost about 13 percent of their leg strength.¹⁶ If you're ill, a few sit-to-stands a day are worth doing once you're up and about. When you come back, start a step lighter and build up again. How to restart training after falling off walks through that.

What changes with a coach on the call

Everything above works on your own, with a chair and a notebook, and it costs nothing. What it leaves to you are the judgment calls, made alone and mid-set: is this weight right, is that a tired muscle or a cross joint, is it time to go up. And then doing it all again in March.

A coach on the call makes them with you. At Bespoke Fit every session is a live 1‑on‑1 video call with your own coach, in our app on iPhone, Android or a browser. Prop the phone or tablet on the kitchen counter and your coach sees what you can't see of yourself.

Here's how that looks on an ordinary Tuesday. You're on the one-arm row, second set. On rep 7 your shoulder starts creeping up toward your ear, and your coach says "shoulder down, elbow to your hip" before rep 8, not next week. Your breathing and heart rate were slow to settle after the step-ups, so you get an extra minute before the calf raises. And because the row went cleanly at 12 twice in a row, Friday's session already has the next weight in it.

That only works if your coach knows you, so each coach has 12 members at most, and we hold to it when we assign coaches. You don't pick from a list. A head coach meets you first on a 30-minute call, which is the place to mention the osteoporosis, the new hip or the blood-pressure tablets, and matches you with a coach. Every coach spends 90 days in onboarding with our founder, Carl, before taking a member.

Sessions run 45 to 90 minutes at the same price, and most people settle at around an hour. You won't be lifting for an hour: it holds the warm-up, the eight moves, the rests between them and the balance work, plus the floor practice once a week, at a pace your coach sets.

"I was skeptical about doing training over video at my age, but it has been much easier than I expected. My trainer is patient and adjusts everything to what my body can handle. I have exercised more in the past two months than in the last ten years. My friends can see the difference."

Wanda, 70, a Bespoke Fit member

What it costs, and who should skip it

It's 14 days free, then $299 a month for as many sessions as you book, and you can cancel anytime. At the twice a week this page recommends, that's about $35 a session. An in-person trainer in the US averages $50 to $90 a session.¹⁷ Where coaching is priced per session, or by sessions a week, every extra session costs more. Here a third one costs nothing extra, so your coach plans the week you need, not the one you can afford.

Skip it if:

• you answered yes on the PAR-Q+ and haven't spoken to your doctor or physio yet. Do that first; a coach isn't a substitute.
• you're in the first weeks after a joint replacement. That's your physio's job, and their exercises come first.
• you want someone in the room to steady you. Your coach watches through your camera, so the counter stays your spotter.
• the plan on this page is already working for you on your own. Keep going; it's free.
• $299 a month would strain your budget. A strength class for older adults at a local community center or Y is a cheaper way to have someone expecting you.

If you do start, the 14 days begin at your first session, not at signup, and a reminder goes out 3 days before the first charge. If you're reading this for a parent: at session time they open the app and join the call, and if they're early, their coach starts it when it's time. Two weeks won't make you much stronger, but it's a fair test of the rest: take the chair-stand test on day one so your coach has your number, and by day 14 ask yourself whether they caught something you couldn't feel.

Common questions

Should I use machines, dumbbells or my own body weight? Any of them works. The American Heart Association notes that body-weight training can be as effective as machines or free weights, so a chair, a wall and a pair of light dumbbells make a complete kit. If you have advanced arthritis, severe osteoporosis, nerve damage (neuropathy) or you've had a stroke, machines are likely the safer choice, ideally with someone showing you how to set them up.

Do I still need cardio? Yes. The guidelines for over-65s pair the two strength days with about 150 minutes a week of moderate activity, like brisk walking. In a five-year Norwegian trial of people aged 70 to 77, the group doing intervals had the fewest deaths, though the gap was small enough to be chance.¹⁸ If you enjoy it, a few faster stretches in your walk are a fine way to get your minutes. Walk, cycle, swim or dance: the kind you'll keep doing is the right kind.
