Mountain Climbing Practice

Mountain Climbing Practice (山登り修業, Yama Nobori no Shugyō) is a training method utilized by and, occasionally,  ninja in order to enhance their own chakra control. By flowing chakra to the soles, the user has to have a fixed level of chakra in order to ensure a grip is made on the mountainous terrain (such as a vertical cliff) or a rock formation, while ensuring that the level of chakra isn't so high that the rock formation begins to break apart under pressure.
