Want to jump higher? Don’t cheat yourself on squats! That’s according to a study published in the Journal of Strength and Conditioning Research. In order to compare how rugby players’ jump height was influenced by squats done to parallel versus quarter-range, researchers first established a baseline, then tested subjects’ three-rep max on one of the two squat variations. Those who squatted lower—till their thighs were parallel to the floor—jumped higher afterward, indicating that neural and muscular activation may be better when squats are performed fully.
