How should you exercise on a GLP-1?

Exercise on a GLP-1 matters most for one reason: protecting lean muscle. Trial data shows 20-40% of weight lost on GLP-1s can be lean mass, and resistance training is the single most effective countermeasure. Prioritize strength work 2-4 times per week — bodyweight, bands, machines, or free weights all count — over pure cardio. Pair it with adequate protein (80-100g/day) so the muscle you're training has material to rebuild. Cardio still helps cardiovascular health and calorie balance, but it does little to preserve muscle on its own. Watch energy: because GLP-1s reduce food intake, some patients feel low-energy during titration; eat a small protein-and-carb snack before training if you feel weak, and stay hydrated since GLP-1s blunt thirst. Don't chase aggressive workout volume in a steep calorie deficit — it backfires with fatigue and poor recovery. If you're over 50 or concerned about sarcopenia, this is worth raising with your provider; some programs (Noom, WeightWatchers) bundle structured muscle-preservation guidance.

Related questions

  • What should you eat on a GLP-1 (and what to avoid)?

    On a GLP-1, eat protein first (80-100g/day to protect muscle), add fiber and extra water, and eat small slow meals. Avoid high-fat and fried foods, large portions, carbonated drinks, alcohol, and refined sugar, all of which worsen nausea on delayed gastric emptying.

  • Can I drink coffee on Ozempic or Wegovy?

    Yes, coffee is fine on Ozempic and Wegovy — there's no interaction between caffeine and GLP-1 drugs. Drink it with food rather than on an empty stomach if it worsens nausea or reflux, and limit sugary coffee drinks that work against the metabolic benefit.

  • What happens when you stop taking Wegovy?

    Wegovy is approved for chronic weight management — meaning it's intended as long-term therapy, not a short course. In the STEP-4 extension trial, patients who stopped Wegovy after a year of treatment regained approximately 67% of their lost weight within a year off the drug, even with continued lifestyle support. The mechanism (appetite suppression) reverses
