In an ascending system, what should be emphasized more, legs or arms?

In an ascending system, the emphasis should primarily be on the use of legs. The legs are generally stronger than the arms and are more capable of providing the power needed to propel oneself upward when climbing. Using the legs effectively allows for a more efficient and energy-saving ascent.

When engaging the legs, climbers can leverage the larger muscle groups in the lower body, which not only helps to conserve upper body strength but also improves overall balance and stability during the ascent. This is particularly important in rescue scenarios where maintaining stamina is crucial for effective performance throughout the operation.

While arms do play a role in stabilizing grip on the rope and providing some assistive pull, over-reliance on them can lead to fatigue and decreased control. Hence, focusing on the legs maximizes upward movement efficiency and decreases the risk of arm fatigue, allowing for a more sustainable climbing technique.
