Re-Build Your Heart with Exercise

We all know that exercise is good for our heart.

What we didn’t know is how and why endurance exercise causes your heart to grow larger and work better in response to the increased pressure and volume.

The Science

According to the research published in Cell, endurance exercise causes a downregulation of a specific transcription factor called C/EBPβ.

This reduction in C/EBPβ kickstarts a genetic program which results in the hypertrophy and proliferation of cardiac muscle.

Ergo, endurance exercise re-builds your heart.
