7. Muscles and Exercise
The act of increasing your muscle mass through exercise is known as muscle hypertrophy, and one of the things you should know about muscles and exercise is the difference between aerobic and anaerobic exercise. If you want to get stronger you should focus on anaerobic exercise and if you want to get fitter, you should focus on aerobic exercise. In anaerobic exercises, the muscles are used up to maximum capacity, improving their power, speed and strength. In aerobic exercise the muscles are not pushed and are working well under their capacity.
