Cardio Ate My Gains

Body Comp comic · June 27, 2026 · 6 slides

Cardio does not inherently destroy muscle gains if recovery, sleep, and nutrition are properly managed. To optimize results, prioritize strength training first in your workouts, adjust the dose of cardio appropriately, and consume enough calories to fuel the extra activity. Ultimately, better cardiovascular conditioning supports more intense and longer weight training sessions.

The GainFrame mascot holds a white flag with a heart and points at a treadmill with teeth-like ridges on its belt that is eating a dumbbell, illustrating the common fear that cardio destroys muscle gains.
