Exercise and Protein: A Guide to Strength Training on GLP-1 Medications
Resistance training combined with higher protein is the best way to preserve muscle on Ozempic, Wegovy, or Mounjaro. Here is a practical guide to getting started.
If you are on a GLP-1 medication like Ozempic, Wegovy, or Mounjaro, adding resistance training to your routine is one of the most impactful things you can do. Research consistently shows that combining strength training with adequate protein provides the best protection against muscle loss during GLP-1 treatment.
A 2025 report by Medscape highlighted that resistance training plus protein may meaningfully lower GLP-1-associated muscle loss. A Frontiers review from the same year reinforced that exercise should be a core part of GLP-1 therapy, not an afterthought.
Why Resistance Training Matters
When you take GLP-1 medications, your body is in a caloric deficit. Without a stimulus to maintain muscle, the body will break down both fat and muscle for energy. Resistance training provides that stimulus. It signals your body: "I need this muscle. Keep it."
Combined with adequate protein (1.0g/lb or 2.2g/kg daily), resistance training can dramatically shift the ratio of fat-to-muscle loss in your favour.
Getting Started: A Practical Programme
If You Are New to Strength Training
Start with 2-3 sessions per week, focusing on basic compound movements that work multiple muscle groups at once:
Sample Beginner Programme (Full Body, 3x per week)
| Exercise | Sets × Reps |
|---|---|
| Goblet squat or leg press | 3 × 10-12 |
| Dumbbell bench press or push-ups | 3 × 10-12 |
| Dumbbell row or seated cable row | 3 × 10-12 |
| Dumbbell shoulder press | 2 × 10-12 |
| Dumbbell Romanian deadlift | 3 × 10-12 |
| Plank | 2 × 30-60 seconds |
Key principles:
- Focus on learning proper form before increasing weight
- Start lighter than you think you need to
- Progress gradually by adding small amounts of weight each week
- Rest 60-90 seconds between sets
If You Have Some Experience
Move to a 3-4 day split to allow more volume and recovery:
Upper/Lower Split (4 days per week)
Upper Body (Monday/Thursday)
| Exercise | Sets × Reps |
|---|---|
| Bench press or dumbbell press | 3 × 8-12 |
| Bent-over row or cable row | 3 × 8-12 |
| Overhead press | 3 × 8-12 |
| Lat pulldown or pull-ups | 3 × 8-12 |
| Bicep curls | 2 × 10-15 |
| Tricep pushdowns | 2 × 10-15 |
Lower Body (Tuesday/Friday)
| Exercise | Sets × Reps |
|---|---|
| Squat or leg press | 4 × 8-12 |
| Romanian deadlift | 3 × 8-12 |
| Lunges or split squats | 3 × 10-12 each leg |
| Leg curl | 3 × 10-15 |
| Calf raises | 3 × 12-15 |
Managing GLP-1 Side Effects During Training
GLP-1 medications can cause nausea, low energy, and reduced appetite, all of which can affect your workouts. Here is how to manage them:
Timing
- Train at least 2-3 hours after eating to reduce nausea during exercise
- Avoid training immediately after your injection day if you experience side effects that day
- Morning sessions often work well before the day's nausea builds
Energy Management
- Reduce volume on tough days - Do fewer sets rather than skipping the session entirely
- A shorter session is better than no session - Even 20 minutes of resistance training provides benefit
- Listen to your body - Adjust intensity based on how you feel
Nutrition Around Training
- Have a small protein-rich snack 1-2 hours before training if possible (Greek yogurt, protein shake)
- Consume 25-40g protein within 1-2 hours after training to support muscle recovery
- Stay hydrated - Sip water throughout your session
The Protein-Training Connection
Resistance training and protein work together. Neither is as effective alone:
- Protein without training - Helps but does not provide the muscle-preserving signal
- Training without adequate protein - Provides the signal but not the building blocks
- Both together - Maximum muscle preservation during weight loss
Aim for 1.0g protein per pound of body weight (2.2g/kg) daily. Use our Protein Calculator with the GLP-1 option to find your exact target.
Tracking Your Progress
Track both your training and nutrition:
- Log your protein with Protein Pal to ensure you are hitting your daily target
- Track your medication with GLP Pal to coordinate training around injection days
- Record your workouts - Track weights, sets, and reps so you can progressively overload over time
Key Takeaways
- Resistance training + protein is the best defence against GLP-1 muscle loss
- Start with 2-3 full-body sessions per week using compound movements
- Progress gradually - Add weight slowly over weeks and months
- Manage side effects by timing workouts and adjusting intensity
- Consume 25-40g protein around training for optimal recovery
- Track everything - Protein intake, workouts, and medication schedule
