Stronger Together
Alloy Personal Training Progress Ridge offers coached small group strength training in Beaverton, Oregon for adults taking a GLP-1 medication such as Ozempic, Wegovy, Mounjaro or Zepbound. The program is built to help protect strength and lean mass during weight loss, with progressive resistance training, habit-based nutrition coaching, and InBody body-composition trend tracking every 30 days. Our coaches never advise on medication; those decisions stay with your prescriber.

Weight loss of any kind commonly includes some loss of lean tissue alongside fat, and after 40 you are already losing muscle to age. On a GLP-1, the weight can come off quickly, which makes the question of what you keep more pressing. This program is our standard small group personal training format, with never more than 6 members in a session and one coach, pointed at a specific job: arrive at a lower weight with your strength, bone, and daily function supported.
The two levers we control are training and measurement. Progressive resistance training, coached, two to three times a week. Standardized InBody scans at your baseline and every 30 days so you can see the direction of travel. Our nutrition coaching handles the third piece, protein and eating habits, at a habit level rather than a clinical one.
If you have questions about dose, timing, side effects, or whether to continue, those belong with the doctor who prescribed the medication. We will work within whatever they tell you.
Across studies of GLP-1 based therapies, the lean-mass share of total weight lost ranges widely, from roughly 15 percent or less in some trials to 40 to 60 percent in others (Neeland, Linge and Birkenfeld, Diabetes, Obesity and Metabolism, 2024). In the SURMOUNT-1 body-composition substudy of tirzepatide, about 74 percent of the weight lost was fat and about 26 percent was lean mass (Look and colleagues, 2025). Lean mass on a scan is not the same as skeletal muscle; it also includes water, organs, and connective tissue.
Trials of resistance training specifically during GLP-1 use are still developing. The strongest related evidence comes from a trial of obese adults 65 and over losing weight through diet: the group that added resistance training lost about 2 percent of its lean mass over six months, versus about 5 percent with aerobic exercise alone, and better preserved hip bone density (Villareal and colleagues, New England Journal of Medicine, 2017). We cover the numbers and their limits in our post on protecting muscle during weight loss on a GLP-1, and the protein side in protein and muscle after 50.
Two or three coached sessions a week. Each session follows your plan: a warm-up, main strength movements (squat, hinge, push, pull, carry) at loads your coach sets and progresses, then accessory work. Your coach tracks what you lift so the load climbs over time. That progression is the point; it is what the related evidence supports.
On a GLP-1 you may be eating much less, and some people feel low on energy or nauseated on certain days. Tell your coach. Sessions get adjusted; they do not get skipped for weeks because one day was rough.
Every 30 days you have an Accountability Session: a standardized InBody scan, a review of your strength numbers, and a plan update. InBody estimates body composition using bioelectrical impedance. It is affected by hydration and measurement conditions, so we read it as a trend across months alongside your strength, measurements, and how you feel, not as proof from a single reading. If your prescriber wants to see the trend, you can share it.
It starts with a Starting Point Session: a conversation and an assessment. We talk through your goals and history, including the medication and anything your prescriber has told you, check how you move, take an InBody baseline, and build a plan. The baseline matters more here than almost anywhere else, because it is the reference point for every scan that follows.
We do not advise on GLP-1 medication: not dose, not timing, not whether to start, stop, or switch. We do not set clinical protein targets or write meal plans; for a personal protein target while eating less, a registered dietitian is the right call. We do not promise a specific body-composition result; some loss of lean tissue during significant weight loss is normal, and the aim is to keep it modest while your strength climbs. Our coaches are fitness professionals, not medical or nutrition providers, and coach-led training complements your medical care rather than replacing it.

Book your intro call, bring your questions, and bring whatever your prescriber has told you.
Yes, please. It changes how we pace sessions, how we handle low-energy days, and what we watch on your InBody trend. You do not need to share your dose or your medical history beyond what affects training. Your coach will never advise on the medication itself; that stays with your prescriber.
Not entirely, and nobody can promise that. Some loss of lean tissue during significant weight loss is normal. Trials of resistance training specifically during GLP-1 use are still developing. The strongest related evidence, a 2017 trial of older adults losing weight through diet, found that adding resistance training cut lean-mass loss to about 2 percent over six months versus about 5 percent with aerobic exercise alone. Progressive resistance training, adequate protein, and consistent monitoring are the practical levers.
Most members train two or three coached sessions a week. That is general programming guidance, not a medical recommendation. If your prescriber has given you specific activity guidance, bring it to your Starting Point Session and we will build around it.
It estimates body composition using bioelectrical impedance. Repeated, standardized scans every 30 days can show an estimated trend over months, alongside your strength numbers, measurements, and how you feel. Results are affected by hydration and measurement conditions, so we treat it as trend data, not proof from a single reading.
At a habit level, yes. Our nutrition coaching helps with routines like getting protein at each meal and eating consistently on days when appetite is low. It is not clinical nutrition. For a personal protein target, especially while eating much less, a registered dietitian is the right call, and medication questions belong with your prescriber.
That decision belongs with your doctor. From the training side, nothing changes: the plan keeps progressing, the scans keep tracking, and the habits you built are the ones that carry forward.
