Most people think cardio is just about burning calories or “getting fitter.” It’s not.

In this episode of Inside The Locker, we break down five overlooked ways cardiovascular training directly improves how you think, work, recover, and age.

If you’ve been treating cardio as optional, this episode will change how you see it.
