How Many Reps and Sets Should You Do on a GLP-1?
5 min read · Updated
The short answer
Two to three sets of roughly eight to twelve reps per movement is a sensible default, and one set is a perfectly good place to begin. The honest part most articles skip: the exact scheme matters far less than the internet implies — the ACSM’s 2026 overview of 137 systematic reviews found that set structure and exercise complexity did not consistently change training outcomes. What counts is that you do enough total work across the week, that the last rep of a set is genuinely hard, and that your form holds. Use the top of your rep range as the signal to add a little load.
The other plan pages cover how many days and which days. This one is the inside of the session: how many sets per exercise, how many reps in each, and how hard the last one should feel.
The default, and why it’s a range
Start with two or three sets of eight to twelve reps for each movement. If you’re completely new, or coming back after a long gap, one set per movement for the first fortnight is not a compromise — it’s a sensible on-ramp that lets you learn the pattern before you add volume. Add the second and third set once the movement feels controlled rather than novel.
It’s a range rather than a number because bodies and movements differ. Ten squats to a chair and ten wall push-ups are not the same ask, and neither is the same for you on a good week and a flat one. Treat 8–12 as the zone you aim for, not a target you must hit exactly.
Why the exact scheme matters less than you think
This is the part worth internalising, because it saves you a lot of reading. The ACSM’s current position stand — an overview of 137 systematic reviews covering more than 30,000 participants — found that equipment type, exercise complexity, and set structure did not consistently change training outcomes. Read the wording carefully: it says these things didn’t consistently matter, not that every scheme is identical. But it does mean 3×10 has no magic in it, and neither does 4×8.
The same logic runs through the frequency evidence: once total weekly work is held equal, how you carve it up stops mattering much. So the useful question isn’t ‘what’s the optimal set scheme’ — it’s ‘am I doing a reasonable amount of work each week, and am I repeating it.’ Sets and reps are just the units you count it in.
How hard should the last rep feel?
Harder than the internet’s ‘3 sets of 10’ usually implies, and easier than failure. A practical marker: finish a set when you think you have one or two reps left in you. That’s enough to make the set count without turning every session into something you dread.
Form is the boundary, not effort. If a rep’s shape breaks down — knees caving, back rounding, a wall push-up turning into a lean — that’s your ceiling for the day, and the set ends there. A grindy last rep with ugly technique isn’t extra credit; it’s the main way beginners get hurt and then stop entirely.
Rest between sets, briefly
Somewhere between one and two minutes is fine for most people, and you don’t need a timer. The workable rule is to rest until your breathing has settled and you’d back yourself to do the next set with the same technique as the last one — which on some days is forty seconds and on others is three minutes.
If you’re short on time, resting less is one of the easier ways to shorten a session, and pairing two movements that don’t compete (a squat and a push, say) lets you rest one while working the other. That’s a scheduling trick, not a requirement.
Sets and reps when you’re eating much less
On a GLP-1 you’re usually running on far less food than you used to, and that lowers the volume you can recover from. So start at the bottom of the ranges — one or two sets, the lower end of the reps — and add rather than trim. Building up from too little is a much easier problem to fix than backing out of too much.
Expect the numbers to move slowly, and don’t read that as failure. A long-standing ACSM guideline puts the progression signal at roughly a 2–10% load increase once you can do one or two reps beyond your target — some weeks you’ll clear that, and plenty of weeks you won’t. Holding your sets and reps steady while your body weight comes down is a real result. If you have a health condition or an injury, or you’re unsure how hard you should be working, check with your healthcare provider before you push the numbers up.
Counting sets is easy; knowing whether the last one was actually hard enough — and still clean — is the part you can’t judge from inside the movement. Mira scores your form through your phone rep by rep, and sets your next session’s numbers from what you actually completed.

How many reps and sets should I do on a GLP-1?+
Two to three sets of roughly eight to twelve reps per movement is a sensible default, and one set per movement is a fine way to start if you’re new or coming back after a break. Add sets once the movement feels controlled rather than novel. The ranges matter more than the exact numbers — the ACSM’s 2026 overview of 137 systematic reviews found set structure didn’t consistently change training outcomes.
Is 3 sets of 10 the best rep scheme?+
There’s nothing magic about it. The current ACSM position stand found that set structure and exercise complexity didn’t consistently change outcomes, and the frequency research points the same way: once total weekly work is held equal, how you divide it up stops mattering much. So 3×10 is a perfectly good default precisely because it’s unremarkable. Pick a scheme you’ll repeat and spend your attention on the weekly total instead.
How hard should the last rep be on a GLP-1?+
Aim to finish a set with about one or two reps still in you — hard enough to count, not so hard you dread the next session. Form is the real boundary: if a rep’s shape breaks down, that’s your ceiling for the day and the set ends there. On a GLP-1 you’re recovering on much less food than before, so start at the low end of the ranges and build up. If you’re unsure what intensity suits you, ask your healthcare provider.
