The final progression of this body weight resistance exercise is to extend hands as high as possible creating a Y shape. The challenge is to drop into the squat
while the hands and arms are kept from tipping forwards.

This also increases stability via increased muscle tone and proprioceptive abilities  which ensures that the risk of twisting your ankles is decreased!
