This Is the Medicine Your Body Creates When You Exercise

When you move your body, especially through strength training or intense muscular contraction, your muscles behave like a pharmaceutical factory, releasing dozens of molecules called myokines that affect nearly every system in the body: the brain, liver, fat cells, immune system, bones, pancreas, and even the gut. During exercise, your muscle fibers release a powerful cocktail of biochemical messengers. These messengers travel through your bloodstream and trigger changes that no medication can replicate.
