The hamstring and calf musculature is commonly tight. A good, quick dynamic stretch that hits both the hamstring and calf muscles is the dorsiflexion toe touch. Simply put the forefoot up on a two-by-four or 2 in. thick book. Then start with the neck and flex the chin to the chest. Proceed downward and flex the trunk in a toe touch stretch. The movement should be slow and steady, not jerky or quick (bouncing). Repeat this movement for 10-12 repetitions and easily prep your muscles for exercise, sports, or just for the day.
