Stretches can be static (exerting force by reason of weight alone without motion) or dynamic (exerting force by reason of weight with motion). Dynamic stretching is advanced and is primarily for
well trained athletes. You should stretch daily and hold each stretch for 15-30 seconds. Perform each stretch 2-3 times. Stretching helps reduce muscle tension, promotes circulation, and relaxes
you. It also improves coordination and body awareness. This is the single most important thing you can do to prevent injury.
