1
Stand with feet hip-width apart, arms at sides or ready for movement. Keep torso upright and core engaged with neutral spine alignment.
2
Prepare by bending knees slightly and positioning arms in a running/athletic stance. Arms should be ready to swing dynamically during the movement.
3
Lower body by bending knees and hips in a squat position, decreasing the angle at the knee joint. Arms can swing backward as body descends into the loading phase.
4
Explosively extend knees and hips to propel body upward off the ground in a vertical jump. Simultaneously drive arms upward to maximize height. Return to standing position and repeat.
