Iso Middle Question

Hi there. 

I'm not quite sure what the goal of this exercise is. During the hold, what muscles should be working? Is pulling the feet towards one another the hold? Should the hips be pressing forward ?

Thank you!

Hi Jesse, the 2 main goals are strengthening muscles at the point of maximum stretch that is the major goal for having the "cold flexibility". Work all the adductors both the mono joint and the dual joint muscles. you should think about pinching the floor on between the feet. Hips do not move.
