The Best Exercise Routine While on GLP-1 Medications

Why Exercise Matters More on GLP-1

Without intervention, roughly 25% of weight lost on GLP-1 medications is lean mass (muscle). This is the single biggest long-term risk of rapid weight loss — losing muscle slows your metabolism and makes weight regain more likely.

The solution is straightforward: resistance training + adequate protein.

The Minimum Effective Dose

You don't need to become a gym rat. Research shows that 2-3 sessions per week of resistance training is enough to preserve nearly all lean mass during GLP-1 weight loss.

A Simple Program (3 Days/Week)

Day A:

• Goblet squats: 3 sets of 10
• Dumbbell rows: 3 sets of 10 each arm
• Push-ups (or dumbbell press): 3 sets of 10
• Plank: 3 sets of 30 seconds

Day B:

• Romanian deadlifts: 3 sets of 10
• Overhead press: 3 sets of 10
• Lat pulldowns (or assisted pull-ups): 3 sets of 10
• Farmer's walks: 3 sets of 30 seconds

Alternate A and B with at least one rest day between sessions.

Key Principles

• Progressive overload: Gradually increase weight or reps over time
• Compound movements: Multi-joint exercises give you the most bang for your buck
• Don't skip legs: Lower body has the largest muscles — biggest metabolic impact
• Rest adequately: Muscle grows during recovery, not during the workout

Cardio: Helpful but Secondary

Walking 7,000-10,000 steps daily is excellent for overall health and mood. But cardio alone won't preserve muscle. Prioritize strength training, add walking as a bonus.

When Energy Is Low

GLP-1 medications can cause fatigue, especially during titration. On low-energy days:

• Do fewer sets (2 instead of 3)
• Use lighter weights
• Focus on just showing up — a 15-minute session beats skipping entirely
• Never skip due to nausea — just reduce intensity

The Non-Negotiable

Combine 80-120g protein daily with 2-3 strength sessions per week. This single combination can reduce lean mass loss to near zero, even during rapid weight loss. It's the highest-impact habit you can build alongside your medication.
