Training Clients on GLP-1s: A Guide for Personal Trainers and Coaches

For personal trainers and coaches

Short answer: clients on a GLP-1 such as semaglutide or tirzepatide eat much less, and some of the weight they lose can be muscle. Your job shifts toward protecting it: regular resistance training, enough protein and fluids, and sessions adjusted around side effects. Medication questions go to the client's prescriber.

What changes when a client starts a GLP-1

  • Appetite drops. Meals get smaller and some clients skip them, which makes it harder to eat enough protein.
  • Side effects come in waves. Nausea, constipation and tiredness are common in the first weeks and after each dose increase, so energy can vary a lot from session to session.
  • Weight comes off faster. Part of any large weight loss is lean mass, not only fat, which is why strength work matters more, not less.
  • Fluids slip. Eating less often means drinking less too, and dehydration makes training feel harder.

Training priorities

  • Make resistance training non-negotiable. At least two days a week of muscle-strengthening work, in line with US physical activity guidelines, with load that progresses over time.
  • Protein first when appetite is low. A 2025 joint advisory from four obesity and nutrition societies puts protein, fibre, fluids and strength training at the centre of care during GLP-1 treatment. The client's clinician or a dietitian sets their own targets.
  • Plan around rough days. Keep a lighter session ready for days after a dose increase or when nausea hits, rather than cancelling.
  • Track more than the scale. Strength numbers, measurements, energy and how clothes fit show whether the weight lost is the weight the client wants to lose.

Stay in scope and keep clients safe

Trainers and coaches shouldn't advise on whether to start a medication, what dose to take or when to switch. Encourage clients to tell their prescriber about big changes in training. Stop and point the client to medical care for severe or lasting stomach pain, repeated vomiting, signs of dehydration or fainting.

Coach clients between sessions

Goprolean Companion is an app your clients can use to log meals, protein, water and habits, and share a weekly summary with you if they choose. Medication details are never shared with coaches. Coaches can apply at app.goprolean.com/partners.

Common questions

Should personal trainers recommend GLP-1 medication to clients?
No. Whether a GLP-1 is right for someone is a medical decision for a licensed clinician. A trainer or coach can explain in general terms what these medications do and suggest the client talk to their own doctor or a telehealth provider.
How should training change for a client on semaglutide or tirzepatide?
Keep resistance training as the priority to help hold on to muscle, make sure the client eats some protein and drinks enough fluid around training, and ease the intensity on days with nausea or low energy. The client's clinician or a dietitian sets their individual nutrition targets.
When should a trainer send a client on a GLP-1 back to their prescriber?
Stop the session and point the client to medical care for severe or persistent stomach pain, repeated vomiting, signs of dehydration such as dizziness or very dark urine, or fainting. Questions about doses, side effects or switching medication also belong with the prescriber.
Is there a Goprolean discount for personal trainers and coaches?
Yes. Certified coaches, personal trainers and fitness industry staff can verify with VerifyPass for 10% off their own first order and every refill at Goprolean.
