Weight training is the quintessential anaerobic exercise. Traditional rope climbing works against resistance provided by body weight. For most climbers, because of strength-to-body-weight ratios, this equates to heavy weight training which results in high anaerobic states.

Aerobic means in the presence of oxygen. In the presence of oxygen both fat and glycogen can be metabolized for energy. Aerobic activities cause an increase in energy demands for the duration of the activities and for a time after.

Once metabolic demand exceeds oxygen supply, the body shifts exclusively to glycogen and lactic acid builds quickly in working muscles. The human body abhors oxygen debt and upon experiencing an anaerobic state the body immediately begins enlarging and strengthening the tissues upon which the demand was placed. Anaerobic activities are responsible for the development of lean mass which translates into increased energy demands 24/7.

You may well ask, "What does this have to do with the Endless Rope machine?" By design the Endless Rope allows an individual to train aerobically or an-aerobically and is so versatile that both modes can be achieved in the same set without making any adjustments to the machine.
