Dynamic stretching is a type of stretching that moves a muscle in and out of a stretched position, as opposed to holding it in its stretch as you would in a static move. For example, a lunge is a dynamic stretch for your quadriceps and hips. Before you’re ready to play or weight train, you need to get your blood flowing to use your muscles. Dynamic stretches can help you greatly in athletic endeavors because they improve your “active” flexibility – that is, they work the muscles and joints in the same way that your sport will. In addition, dynamic stretches will increase your heart rate, helping you gear up for your workout. Jumping jacks, squats, lunges, and high knees are all examples of dynamic stretches. You can perform these moves as a circuit before any type of exercise to help you warm up and prevent injury. Complete one set of 10 repetitions per exercise, then move on to the next dynamic stretch. And make sure to do your static stretches after your workout or on days when you’re not gearing up for a workout but want to keep limber.
