GLP-1 Exercise Pairing Configurator

Give it your fitness level, your age, what you are training for and how long you have been taking the drug, and it returns a week: lifting days, cardio minutes, a step target, and the protein underneath all of it. The reason to bother is in S-LiTE, where training alongside the drug took off 40% more than the drug by itself.

Five patterns: a squat; a hinge, meaning a deadlift or an RDL; a push across the body, dumbbell press or push-up; a pull across the body, row or pull-up; and something carried, whether a farmer carry or a sled push. Sets of 8 to 12 reps, 2 to 4 sets each, and add a little every week.

Two days a week of compound, multi-joint lifting is the floor ACSM set in 2011 (Garber, PMID 21694556). Put enough protein alongside it and lean mass is not merely defended but added, even while eating at a deficit — that is Mettler 2010 (PMID 19927027) and Longland 2016 (PMID 26817506).

HIIT

1 day/wk

25 min/session

Between 4 and 8 bursts of 30 to 60 seconds, each near flat out, each followed by an equal rest. A stationary bike, a rower, a hill, or sprints will all do it. The appeal is how little time it takes.

Wewege 2017 (PMID 28401638) found intervals and steady moderate cardio take off much the same body fat — the interval work simply gets there in about 40% less time.

Walking

5 days/wk

45 min/session

Walk briskly, hike, or take any low-impact cardio at a moderate effort. The target is 10,000 steps a day, counting both deliberate walks and everything you accumulate without thinking about it.

Walking is not a lesser option. Against 4,000 steps a day, 8,000 halved mortality — a 51% reduction in Saint-Maurice 2020 in JAMA (PMID 32207799) — and 12,000 improved on that again. Murphy 2007 (PMID 17275896) puts the threshold for real change in weight and BMI at more than 150 minutes a week.

Mobility

2 days/wk

30 min/session

Pilates, yoga, foam rolling, guided mobility. None of it is here to burn anything. It is here for recovery, for range of motion, and for stress — and indirectly for lean mass, because what you can recover from is what you can lift again.

The evidence is honest about its limits: Aladro-Gonzalvo 2012 on Pilates (PMID 22196436) and Lauche 2016 on yoga (PMID 27058944) both show weak effects on weight, and real ones on stress, flexibility and quality of life.

Estimated weekly calorie burn

~2,675 kcal

A rough figure, and only there for encouragement. What you actually burn moves with your weight, how hard you work, and how well you recover.

Caveats and safety notes

· From month 3 the cost of skimping on protein or lifting starts to add up in lost lean mass. A DXA scan around month 6 tells you what is actually happening rather than what the scale implies.
· Go more than 500 kcal a day under maintenance and lifting stops adding lean mass — Murphy and Koehler 2022 (PMID 34623696). The trouble is that a GLP-1 hides under-eating by removing the hunger that would otherwise tell you. Count calories and protein through the first 3 to 6 months.

Why these recommendations

· Training alongside the drug beat the drug on its own in S-LiTE (Lundgren, NEJM 2021, PMID 33951361): -9.5 kg against -6.8 kg, which is roughly 40% more weight off in the combined arm.
· For weight loss that counts clinically, ACSM's 2009 position stand (PMID 19127177) puts the bar above 250 minutes of moderate activity a week.
· Nothing protects lean mass through GLP-1 weight loss the way lifting does when there is enough protein behind it. See Cava 2017 (PMID 28507015), and Neeland 2024 (PMID 38937282).

Why exercise pairing matters on a GLP-1

The body-composition substudies inside the GLP-1 trials found that, left alone, between 25 and 45% of what comes off is lean tissue. Nothing counters that as well as lifting with enough protein behind it. The S-LiTE trial (Lundgren NEJM 2021, PMID 33951361) randomized 195 adults to liraglutide alone, exercise alone, or both combined, and the combination produced −9.5 kg vs −6.8 kg with the drug alone — 40% bigger weight loss with roughly double the body fat reduction.

How the configurator works

Nothing below is a rule of thumb — each one traces to a paper:

Resistance training days: The floor is 2 to 3 days a week of compound, multi-joint lifting, set by the ACSM 2011 position stand (Garber, PMID 21694556). Where the goal is holding lean mass, this raises it to 3 or 4.
Cardio minutes. For weight loss that counts clinically, the ACSM 2009 position stand (Donnelly, PMID 19127177) asks for more than 250 minutes a week at moderate intensity. Between 150 and 250 covers a modest goal, or holding steady.
Step target: The turn comes at 8,000 steps a day: against 4,000, that halved mortality in the Saint-Maurice 2020 JAMA cohort (PMID 32207799), a 51% reduction. Twelve thousand improved on it again.
Intervals against steady cardio. Wewege's 2017 meta-analysis (PMID 28401638) found the two produce the same fat loss, with intervals taking about 40% of the time. Held back here until someone is past the opening 4 weeks and training at an intermediate level or above.
Protein target: Neeland 2024 (PMID 38937282) sets 1.6 to 2.3 g/kg of fat-free mass for anyone on a GLP-1. Since few people know their fat-free mass, that is translated cautiously here into 1.4 to 2.0 g/kg of total body weight, varying with goal and age.
Deficit ceiling caveat: Murphy & Koehler 2022 (PMID 34623696) showed deficits >500 kcal/day below maintenance impair lean mass gains during resistance training. GLP-1 appetite suppression can mask under-eating; track calories and protein.

Important disclaimer

This configurator is for educational purposes only and does not constitute medical advice or an exercise prescription. Patients with cardiovascular disease, joint pathology, or other conditions limiting exertion should consult a clinician (and ideally a credentialed exercise physiologist or physical therapist) before starting any new exercise program. The S-LiTE trial used liraglutide 3 mg specifically; the directional inference to semaglutide and tirzepatide is reasonable but not yet replicated in a head-to-head trial. Every primary source cited here was independently verified against PubMed by a research subagent on 2026-04-08.
