Correspondingly, the five phases that can be described between these positions are as follows: (1) the first pull happens between the ground and when the bar reaches knee level and is initiated by knee and hip extension; (2) the transition happens when the barbell is between knee level and the power position and involves a shift in the position of the body relative to the barbell, which involves a brief period of knee flexion and is therefore referred to as the double knee bend (Enoka, 1979; 1988); (3) the second pull is the most powerful phase of the lift and occurs while the barbell is between the power position and the lifter is in triple extension; (4) turnover occurs as the lifter quickly drops down under the bar from the triple extension position to the catch position, in a deep front squat; (5) recovery into the standing position occurs as the lifter stands from the catch position to upright.
