Exercise Cleans Muscles.

According to a new study, an intense ten-minute bout of exercise increases the activity of the “death marker protein” called ubiquitin, which helps remove worn-out proteins from muscle tissue. Researcher Dr. Jørgen Wojtaszewski writes, “Basically, it explains part of the reason why physical activity is healthy. The beauty is that muscle use, in and of itself, is what initiates the processes that keep muscles up to date, healthy, and functional.”
