Single-Leg Calf Jump (StepBox Supported)
The single-leg pogo with the free foot resting on an aerobic step beside you; the support takes out the balance so the ankle can spring.
How to do it
Setup
One foot on the floor, the other resting on a low aerobic step, hands on the hips.
Steps
- Bounce off the ball of the floor foot, knee nearly straight.
- Let the foot on the step only steady you, not push.
- Keep the bounces quick and low; switch legs after the set.
Common mistakes
Pushing off the step foot: it rests; the floor leg does every bounce. Heel of the working foot touching down: stay on the ball of the foot. Sinking into the knee: stay tall and let the ankle spring.
Breathing
Fast steady rhythm.
