Supported Single-Leg Calf Stepbox Jump

Stand facing a step box and place one foot securely on top while keeping the opposite foot resting on the floor behind you for support.

Engage your core and maintain an upright posture with your hands resting on your hips.

Push through the ball of your front foot to perform a quick, explosive hop upward off the step.

Land softly back onto the ball of the same foot, immediately letting your heel dip down to load the calf muscle for the next repetition.

Complete all repetitions on one side before switching to the opposite leg.
