1
Stand with feet hip-width apart, arms at sides or ready position. Maintain upright posture with neutral spine and engaged core.
2
Bend knees and hips to lower body into a quarter squat position, preparing for explosive upward movement. Arms can swing forward for momentum.
3
From the lowered squat position, control the downward phase by allowing knees and hips to flex, descending with controlled tempo. Keep chest upright and weight distributed through midfoot.
4
Explosively extend hips and knees simultaneously, driving through feet to propel body upward into vertical jump. Fully extend legs at top, then land with soft knees, absorbing impact through eccentric muscle contraction.
