You know you should be lifting on a GLP-1. What almost nobody hands you is the how: which exercises, how many sets, how heavy, and how to make it harder over time without getting hurt. This is that plan. It's general fitness education, not a prescription, and it's built for someone who has never followed a structured program.
A quick word on the evidence. Resistance training is the best-supported way to protect muscle while you lose weight, but direct trials in people on GLP-1 medications are still few, and some lean-mass loss is expected with any large weight loss. If anything, that's a reason to train well and consistently.
Start with five movement patterns
Beginners get lost trying to memorize dozens of exercises. Don't. Almost everything worth doing falls into five patterns, and a good week touches all of them:
- Squat: bending at the knees and hips to lower and stand back up (bodyweight squat, goblet squat, leg press).
- Hinge: bending mostly at the hips with a flat back (hip hinge, glute bridge, Romanian deadlift).
- Push: pressing weight away from you (push-up, dumbbell or machine chest press, overhead press).
- Pull: pulling weight toward you (row, lat pulldown, assisted pull-up).
- Carry: picking something up and walking with it (farmer's carry, suitcase carry), which trains your grip and core.
Pick one exercise per pattern that you can do with good form, and you have a full-body workout.
A simple full-body template, 2–3 times a week
The Physical Activity Guidelines for Americans recommend muscle-strengthening activity working all the major muscle groups on at least two days a week. Treat that as your floor. The American College of Sports Medicine (ACSM) suggests 2–3 days a week for beginners (DOI (external link)), so three is fine if you recover well. As a beginner, one full-body session repeated 2–3 times a week beats a complicated split, because each pattern gets several practice runs a week while you're still learning the movements.
A session looks like this:
- Squat: 2–3 sets
- Hinge: 2–3 sets
- Push: 2–3 sets
- Pull: 2–3 sets
- Carry or a core exercise: 1–2 sets
Leave at least one rest day between sessions (for example, Monday/Thursday, or Monday/Wednesday/Friday). The workout should take 30–45 minutes. If it's taking much longer, you're resting too long between sets or doing too much.
Sets, reps, and what "progressive overload" really means
For beginners, the ACSM recommends loads you can lift for about 8–12 repetitions, and for building muscle it suggests resting 1–2 minutes between sets (DOI (external link)). A common starting point is 2–3 sets of 8–12 reps per exercise. The exact rep count matters less than effort: a 2017 meta-analysis found that lighter and heavier loads built similar amounts of muscle when sets were pushed hard, though heavier loads built more maximal strength (DOI (external link)). Anywhere from about 6 to 15 reps works if you push reasonably hard.
The principle that makes it all work is progressive overload: gradually giving your muscles more than they're used to, so they have a reason to adapt. Nothing changes if every workout is identical forever. You add a little over time by:
- adding weight when the current load gets easy,
- adding a rep or two within your target range,
- adding a set, or
- improving your form and range of motion.
A practical beginner rule: when you can complete the top of your rep range with good form on every set (say, 3 sets of 12), add a small amount of weight next time and drop back toward the bottom of the range. Then climb again. The ACSM describes the same idea: raise the load by about 2–10% once you can do one or two reps more than your target. Up in reps, then up in weight, repeat. That slow ratchet is how you get stronger.
Judge effort by reps in reserve
You don't need to train to failure to make progress, and as a beginner you shouldn't. A 2022 meta-analysis of 15 studies found no significant difference in strength or muscle growth between training to failure and stopping short of it (DOI (external link)). Use "reps in reserve" (RIR): how many more reps you could have done before your form broke down. A common coaching convention (not a tested rule) is to finish most sets with about 2–3 reps in reserve. The set should feel challenging, but you could have squeezed out a couple more. That's the range between too easy to matter and so hard your technique falls apart. If the last rep looked ugly, you went too far; back off the weight.
Why the deficit raises the stakes
This is the part specific to a GLP-1. When you lose weight quickly, some of what comes off is lean tissue, much of it muscle. In recent trials, lean tissue made up roughly 25–40% of total weight lost on these medications (DOI (external link)). Being in a calorie deficit, and often eating less protein than usual, is exactly when muscle is most vulnerable.
Resistance training is the signal that tells your body to hold on to muscle while fat comes off. In a randomized controlled trial of patients on a 12-week protein-supplemented very-low-calorie diet, the group that added resistance training three days a week lost almost no lean mass. About 4% of their weight loss came from lean tissue, versus roughly 24% in the diet-only group, and they lost just as much fat while better protecting their resting metabolism (DOI (external link)). A separate meta-analysis found that in a calorie deficit, resistance training reliably preserves strength even when building new muscle is harder. A deficit of about 500 kcal/day was enough to stop lean-mass gains, so the authors advise avoiding deficits larger than that when the goal is preserving muscle (DOI (external link)). Adequate protein helps too. In a meta-analysis of 49 trials in healthy adults, protein supplementation added modestly to the gains in muscle and strength from resistance training (DOI (external link)). Those trials weren't done in a calorie deficit or on a GLP-1.
Progression, deloads, and not overcooking it
Add difficulty gradually; a small jump every week or two is plenty. Progress is rarely linear, and stalling for a session or two is normal.
Many coaches build in a deload: an easier week with lighter loads or fewer sets, so your body can recover and catch up. In interviews, strength and physique coaches said they usually program one every 4–6 weeks, though timing varied a lot (DOI (external link)). Competitive lifters in a 2024 survey reported deloading about every 5.6 weeks, and also when performance stalled or their joints ached (DOI (external link)). There's little trial evidence behind a fixed schedule, so it's also reasonable to take one when sleep is poor or the weights suddenly feel heavier than they should. On a GLP-1, weeks with strong nausea or low appetite are natural deload weeks. Scale back to bodyweight movements instead of skipping entirely.
Safety and when to bring in help
- Put technique before load. Master each movement with light or no weight before adding plates. Bad form under heavy load is the fastest route to injury and quitting.
- Warm up with a few minutes of easy movement and a lighter set of each exercise.
- Stop any exercise that causes sharp or joint pain. Muscular effort is fine; pain is not.
- Check with your clinician before starting, especially if you have cardiovascular disease, joint problems, or significant GI side effects.
If you're unsure whether your form is safe or your program is doing enough, consider some coaching. Even a few starter sessions to learn the patterns can be worth it. Whatever route you take, do the strength work, get a little better than last time, and protect the muscle you have.
