1
Stand upright with feet hip-width apart, arms at sides or held for light balance support. Maintain neutral spine and engage core throughout the exercise.
2
Position feet shoulder-width apart with weight distributed evenly. Prepare by standing on flat ground with no external load, ready to perform explosive upward motion.
3
Lower the body by allowing heels to contact the ground after the jumping motion, eccentric loading of the calf muscles as bodyweight is decelerated upon landing.
4
Explosively drive through the balls of the feet, extending ankles and rising up onto toes while propelling body upward in a jumping motion. Return to starting position and repeat continuously.
