A dynamic stretch is a series of challenging motions that are executed repeatedly so that the stretch is felt further with each motion. These stretches entail a lot of motion and are not necessarily deep stretches, so they can be done safely prior to warming up the muscles or even as a warm-up exercise. Athletes often use dynamic stretches to prevent injury and to loosen up the joints and muscles prior to a strenuous workout.
A static stretch is a deep, slow stretch, which entails a singular motion held in place for ten seconds or more. These are the types of stretches to do when you are aiming for extreme flexibility or are just beginning to learn to stretch. Remember to take it easy and to warm up the muscles prior to a static stretch in order to prevent injury. Thats the Diffrences
