Training on a GLP-1 changes the equation.

Evidence-based guidance for athletes navigating training, fueling, recovery, body composition, and performance while using GLP-1 medications.

Cycling

Power, pacing, and fuel on the bike.

Gut-friendly fueling from easy miles to race day.

Carbs, electrolytes, and hydration timing.

Keep lean mass while the scale drops.

Sleep, repair, and returning to form.

How these medications affect training.

GLP-1s can blunt thirst, slow gastric emptying, and change sodium handling. What to drink, when, and how much.

It is not the drug. It is glycogen. Here's how appetite suppression drains your tank mid-workout and how to fix it.

Fueling for rowing and erg sessions on semaglutide or tirzepatide. High-intensity, high-sweat, repeat-effort nutrition.

Protein has a job. Carbohydrate has a job. Fat matters too — but for athletes, its target makes more sense when you look at the whole energy picture.

Carbohydrate is the primary fuel for harder training. When a GLP-1 makes eating less automatic, athletes need to make fueling more intentional.
