What characterizes a hand release pushup?

A hand release pushup is characterized by the requirement to lift the hands off the ground at the bottom of the movement, which is a key element that distinguishes it from a traditional pushup. In this variation, the exercise begins from the ground with the chest touching the floor, and as the individual pushes up, they must release their hands momentarily before bringing them back to the ground to complete the motion. This emphasizes not only the strength required for the upward motion but also the control needed to handle the hand release at the bottom.

The other options describe different types of pushups that do not align with the specific mechanics of a hand release pushup. For instance, starting from a standing position is not a traditional pushup at all, while elevated legs would reference a decline pushup, which alters body angle, and performing on one leg either refers to a one-legged pushup variation or stability challenge, neither of which involve the hand release technique. Thus, option C accurately captures the essence of a hand release pushup.
