Active Stretching vs. Static Stretching

Static stretching done just before activity can reduce your power output and increase your risk of certain injuries. Instead, perform an active warmup that gets your body ready for exercise with exercise, increasing your heart rate, firing up your nervous system, and getting your muscles used to moving. For an easy routine, perform a 5-minute warmup of basic, body weight moves—lateral slides, pushups, squats and lunges.
