The biomechanical analysis of this exercise reveals that it's almost 100% quadriceps loading, and virtually 0% gluteus loading. This is due to the conversion of the direction of resistance from "straight down" (vertical) to a rotational force, which creates an opposing (perpendicular) "ground reaction force" against the front of the ankle - despite the lower leg remaining in the vertical position.
