Trick of Squat Jump

Begin by flexing downward to a half-squat position; immediately check this downward movement and explode upward as high as possible, extending the hips, knees, and ankles to maximize length as quickly as you can. Initially, freeze the landing, check for quality; then you can reset and begin another repetition. Progress from the single response to the multiple with a pause sequence of repetitions, then finally to multiple responses, initiating the jumping phase just before reaching the semisquat position. Work for maximum height for each jump
