Muscles ONLY contract!!! Muscles move bones closer together (Concentric), keeps bones still (Isometric), or bring bones back to their original position (Eccentric) . Muscles do not stretch, they are just eccentrically contracting when you feel the "stretch". When Exercising, think of what muscles you want to focus on, squeeze those muscles, and let's the muscles move your bones with control or let them hold you still!!!
