Dynamic stretches are different from static stretches. Static stretches are meant to pull and hold your muscle in place. Dynamic stretches move your muscles and warm them up by getting them working. When you think dynamic stretches, think about jump rope, squats, lunges and jumping jacks. For your arms, try hugging motions and arm rotation. If it feels like you are getting your body up and moving, it is likely a dynamic stretch.
Compare your muscles to rubberbands. When it’s cold or your movement is constricted, they are tightly wound. By warming them up, you’re allowing your body to prepare itself for some big time movement. Once you feel like your muscles are loosened, your warm up is done.
