Quicker boulder sends through power spotting

A dilemma in bouldering is that you can't hang in a quick draw while working the crux. However, if the hardest part is within reach from the ground, your partner can assist you by simply eliminating some weight by pushing you on the back, i.e. power spotting.

This means you can get a feel for how to do the crux, or simply save some energy on the moves before the crux or the top out. Another possibility is to hold the foot and push it towards a small edge, so that it does not slip.
