WHOLE BODY WARM UP

117. WHOLE BODY WARM-UP Even though it may be chest day or leg day, keep mind that your heart and lungs are going to play an integral part. Always perform five to ten minutes of general cardio to bring the heart and lungs up to speed. This ensures full circulation and oxygen delivery to the muscles when you hit the weights. Popular cardio machines for warm-ups include the treadmill, rowers, stationary cycle, and, in recent years, the elliptical or crosstrainer.
