Will Cardio Kill Your Gains?

Body Comp comic · June 8, 2026 · 6 slides

Cardio does not destroy muscle gains when done in moderation and programmed correctly. For best results, perform low-intensity cardio after weightlifting sessions to aid recovery and support heart health. This approach ensures cardiovascular fitness without compromising strength or muscle growth.
