Knee Pushup — Hands Elevated
The knee pushup performed with hands elevated strengthens the chest, shoulders and triceps. The elevation increases the exercises range of motion and allows for a pre-stretch on the chest muscles. The pre-stretch is believed to contribute to greater force production by the muscles. Following a pre-stretch (eccentric contraction followed immediately by a concentric contraction) the muscles utilize the storage of elastic energy to achieve a peak-contraction.
