Scientists Reveal How Exercise Benefits Every Part of Your Body

Researchers say exercising muscles release myokines and other exerkines that act as body-wide signals.

These molecules can boost immune function, brain plasticity, glucose and fat metabolism, and cardiovascular health.

Exercise therefore benefits far more than muscles, helping lower disease risk and mortality.

The review highlights signals such as IL-6, BDNF, irisin, and cathepsin B in the muscle-body connection.
