We tracked 70,000 GLP-1 user activities to see what Ozempic does to your training

The fitness cost of GLP-1s is real — resting heart rate goes up, HRV drops, recovery gets worse.

The surprising part: fitter users who exercised more could partially offset the heart rate increase, but no amount of training could counteract the HRV suppression. Your parasympathetic recovery takes a hit regardless.
