GLP-1 and Exercise: Building the Right Routine

Resistance training is the most important exercise on GLP-1. Without it, you\'ll lose muscle along with fat.

Why Resistance Training Matters

Without resistance training during GLP-1-induced rapid weight loss, 25-30% of weight lost can be lean mass (muscle, organ tissue). Lean mass preservation requires a stimulus signal: lifting weights tells your body to keep muscle, even in a caloric deficit.

The Right Routine

2-3 resistance sessions per week. Focus on compound lifts (squats, deadlifts, presses, rows). 3-5 sets per exercise.
7,000-10,000 daily steps. NEAT (non-exercise activity thermogenesis) drives a meaningful share of total energy burn.
1-2 cardio sessions per week. 30-45 min Zone 2 (conversational pace) cardio for heart health.

Fueling Around Workouts

Eat 30-60 min before training: protein + simple carbs (yogurt + berries, protein shake + banana)
Hydrate aggressively — 16-20 oz water 1 hour before
Post-workout: protein + carbs within 60-90 minutes

Frequently Asked Questions

Best exercise on GLP-1?

Resistance training 2-3x per week is the most important exercise on GLP-1. It preserves lean mass during weight loss. Add 7,000-10,000 daily steps and 1-2 cardio sessions for cardiovascular benefit.

Why do I have low energy for exercise on GLP-1?

Reduced calorie intake combined with low electrolytes during early weeks. Solutions: hit protein targets, eat 30-60 minutes before workout, take electrolytes, slow titration if symptoms severe.
