Strength training on a GLP-1: two sessions, six movements

Protein gives your body the material to keep muscle. Training gives it the reason. This is the smallest amount of work that reliably does the job, written for people who are eating very little.

The short answer

Two 30-minute full-body sessions a week, covering six movements: a squat pattern, a hinge, a push, a pull, a carry and a core brace. Enough load that the last two repetitions are hard. That is the minimum dose that holds a strength test steady while you are losing weight, and it is a dose almost anyone can fit into a week.

Why protein on its own is not enough

Protein gives your body the material to keep muscle. Training gives it the reason. In a large calorie deficit the body is deciding what to keep and what to break down for fuel, and muscle that is not being asked to do anything is the obvious candidate. A strength session is the message that says this tissue is still in use.

The pooled trial data puts a number on it. Across 20 randomised trials, an average of 35.2% of the weight lost on semaglutide (Ozempic, Wegovy) was lean mass. Losing the same weight through diet alone cost 26.2% as lean mass, which was not significantly different from the medications (p = 0.42). The muscle comes off because the weight comes off, not because of the injection. Adding resistance training brought it down to 17.5%, the most favourable result of any approach studied. Eisa N et al, Diabetes, Obesity and Metabolism 2026

That last figure is the entire case for this page: the most favourable result of any approach in that analysis, and it came from people lifting something twice a week rather than from a different molecule or a cleverer diet. Supervised resistance training for longer than 10 weeks has produced gains of around 3 kg (6.6 lb) of lean mass and around 25% in strength in adults. Locatelli JC et al, Diabetes Care 2024

Walking is not a substitute. It is excellent for your heart, your head and your daily energy use, and it sends almost no signal to keep muscle. If you have added 8,000 steps a day and nothing else, you have made yourself fitter and you have not protected a gram of lean tissue.

The six movements

Every session covers the same six patterns. The exercises inside them can change with your equipment, your joints and your confidence.

  • Squat pattern Sit-to-stand from a chair, goblet squat, leg press. Legs, and the single best predictor of staying independent later.
  • Hinge Romanian deadlift, hip hinge to a chair, glute bridge. Backside and hamstrings, and where most people are weakest.
  • Push Wall or bench push-up, dumbbell press, machine chest press. Chest, shoulders and the back of the arm.
  • Pull Band row, dumbbell row, lat pulldown. Upper back and the front of the arm, and the fix for posture.
  • Carry A weight in each hand, walk 20 metres (22 yards). Grip, trunk and shoulders in one movement that needs no technique.
  • Core brace Plank, dead bug, suitcase hold. Bracing rather than crunching, which spares your back.

The two sessions, written out

Session A: goblet squat, 3 sets of 8. Dumbbell row, 3 sets of 10 each side. Push-up on a bench or the floor, 3 sets to two short of failure. Suitcase carry, 3 walks of 20 metres (22 yards). Plank, 3 holds of 30 seconds. Rest 60 to 90 seconds between sets.

Session B: Romanian deadlift, 3 sets of 8. Dumbbell shoulder press, 3 sets of 8. Lat pulldown or band pulldown, 3 sets of 10. Split squat, 2 sets of 8 each leg. Dead bug, 3 sets of 8 each side.

Both sessions fit in 30 minutes if you keep moving, and both work with a pair of dumbbells, a resistance band and a chair. At a gym, swap the free-weight versions for machines without losing anything that matters at this stage.

Starting from nothing

If you have not trained in twenty years, start here and ignore everything above for a fortnight. Sit-to-stand from a dining chair, as many as you can manage in 30 seconds. A push-up against the kitchen bench, 8 repetitions. A row with a resistance band looped around a door handle, 10 repetitions. A carry with two shopping bags, the length of the hallway. Two rounds. Twice a week.

That is a real session. It builds the habit, it teaches the patterns, and it produces the first month of progress, which is mostly your nervous system learning rather than muscle growing. From there you add a round, then a weight. Our guide for people starting over 60 covers the same ground with more attention to balance and joints.

How to progress, and what hard means

The rule is simple: the last two repetitions of every set should be difficult while your form stays clean. If you finish a set of 10 and could have done 10 more, the load is too light to send any signal at all. This is where most people on a GLP-1 undertrain, because they are cautious and tired and the weights feel heavier than they used to.

Progress in this order. First add repetitions, up to about 12. Then add weight and drop back to 8. Then repeat. On the squat and the hinge that might be 2 kg (4.4 lb) at a time; on the press it might be 1 kg (2.2 lb). Write down what you did, because in a deficit you will not remember and you will drift downwards without noticing.

Training when you have no energy

Three practical adjustments. Train on the days your appetite is best, which on a weekly injection is usually days four to seven. Eat something with protein and some carbohydrate beforehand, even if it is only a shake and a banana. And shorten rather than skip: two rounds instead of three still counts, and a 15-minute session done is worth more than a 45-minute session imagined.

If you are flat every single session, the problem is usually intake rather than training. See fatigue and low energy on a GLP-1, and check your total food before you conclude you need more rest. Stop and speak to your prescriber if you get chest pain, feel faint, or your heart races during exercise.

Equipment, and what you can skip

A pair of adjustable dumbbells, a long resistance band and a sturdy chair will run this programme for a year. If you are buying once, buy dumbbells that go to at least 12 kg (26 lb) each, because you will outgrow 5 kg (11 lb) within two months on the squat and the hinge. A gym membership buys you machines, which are easier to learn and easier to load heavily, and neither is required.

You can skip almost everything else. Wobble boards, vibration plates, ab rollers and most classes marketed at people over 50 are not resistance training in the sense that matters here. The test is whether the last two repetitions are hard against a load you can measure and increase.

Soreness, joints and recovery in a deficit

Expect two to five days of soreness after the first couple of sessions, then much less. Soreness is not the goal and it is not the measure; the logbook is. Recovery is slower on very low food, so keep the two sessions at least two days apart, sleep as well as your evenings allow, and do not add a third session until the first two feel comfortable for a month.

Joint pain that stays after the session, rather than fading within a day, means the load or the range is wrong for you at the moment. Shorten the range, reduce the weight, and see your doctor or a physiotherapist if it persists. Training around a painful joint is a skill worth getting help with rather than working out alone.

Why we ask you to test yourself, rather than trust a scan

Here is the gap in the research, and it is the reason this site exists in the shape it does. In a 2026 review of 35 studies in the Annals of Internal Medicine, not one reported whether people could actually do more or less afterwards. Scans were measured. Getting out of a chair was not. Batsis JA et al, Annals of Internal Medicine 2026

Body composition was measured carefully and function was not measured at all. So nobody can tell you from the published work whether the tissue you keep translates into standing up, carrying things or climbing stairs. We are not going to pretend otherwise, and we are not going to diagnose anything from a home test either. What we do instead is track your own number over time: the same movement, the same way, every week, compared with you a month ago and nobody else.

How to know it is working

One strength test, the same way, every week. The 30-second sit-to-stand if you are starting out, or goblet squat repetitions at a fixed weight if you are training. Fat loss does not make you weaker, so a number that falls three or four weeks running is a real signal, and it is fixable with protein and load. Alongside it, your seven-day protein average and a tape measure around the upper arm.

Set your protein target with the calculator, keep the cheat sheet on the fridge, and if strength is already sliding, start with feeling weak and losing strength.

Questions people ask

How much strength training do I need on a GLP-1?

Two 30-minute full-body sessions a week, covering a squat pattern, a hinge, a push, a pull, a carry and a core brace. More is fine if you have the energy. Less than twice a week rarely holds a strength test steady in a large deficit.

Does resistance training actually protect muscle on a GLP-1?

It is the one thing in the pooled data that moved the number. Adding resistance training brought it down to 17.5%, the most favourable result of any approach studied. For context, the same trials put the figure at 35.2% on semaglutide and 26.2% for diet alone.

Is walking enough to protect muscle?

No. Walking is good for your heart and your daily energy use, and it sends almost no signal to keep muscle. You need resistance that makes the last two repetitions hard.

Should I train on injection day?

Train on the days you feel best, which on a weekly injection is usually later in the week. If injection day is your worst day, move the session rather than skipping the week.

I have never lifted weights. Where do I start?

Chair sit-to-stands, bench push-ups, a band row and a carry with shopping bags. Two rounds, twice a week. Add a round, then add weight. Check with your doctor first if you have heart or joint problems.

Will strength training stall my weight loss?

It may steady the scale for a few weeks while your body composition improves, which is the point. Judge it on the waist tape and the strength test rather than the number on the scale.

Why two sessions, and what the research cannot tell you

Two of these are the argument for training. The third is the hole in the literature that the weekly test is our answer to.
