Workouts Can Alter Your DNA

New studies in the March issue of cell metabolism shows that when people exercise for something as little as a 20 minute workout, it can alter their DNA almost immediately.  The main genetic code isn't change, for example you won't go from having blonde to brunette hair.  This means that the DNA molecules within your muscles are structurally changed at specific locations.  The research concluded that changed, known as "epigenetic modifications," seem to be the early precursor to the genetic reprogramming of muscle for strength, structure and the metabolic benefits of exercise.  The researchers also found out hat caffeine can change muscles in the similar ways.  The ones that had been exposed to caffeine showed fewer DNA chemical marks than they did before exercise.   As said my Zierath, a researcher, "Exercise is medicine."
