Limited Edition 8lb Chrome Burn Machine Speedbag

The Speed Bag is designed to increase cardio and muscular endurance. The handles rotate freely to facilitate a high-repetition exercise, while the weight of the unit provides a resistance to the force of the muscle contraction, which helps to strengthen and tone muscles. The signature exercise for which the Speed Bag was designed emulates the punching movement of a conventional boxer's workout. This movement raises the heart rate and provides a cardio-intensive workout, while the weight of the unit works to tone and strengthen muscles. The level of intensity of the Speed Bag workout can be adjusted by the speed of the exercise performed as well as the position in which the unit is held. For example, the higher the elbows, the more challenging the exercise; also, holding the unit closer to the body decreases resistance. When working to increase stamina, the user should employ various positions and speeds to create an interval workout. Interval workouts involve alternating higher intensity intervals with recovery intervals for a sustained period of time. The Speed Bag is also intended for use in circuit training. By using the Speed Bag in short, high cardio-intensive bursts between each set of a weight-training session, the user can increase and maintain an elevated heart rate for the duration of their strength training workout, thus increasing the muscles' capacity for oxygen consumption. This process pushes the muscles to work more efficiently, burn more calories during the workout, and improves the body's metabolism.
