How to Perform
- Begin in a front stance with the punching hand at the hip.
- Step through with the rear foot, keeping the hips level and the centre of mass low.
- Deliver the punch so that it arrives exactly as the stepping foot lands.
- Finish in a stable front stance with the punch extended and the other hand withdrawn.
Coaching Cues
- “The punch lands when the foot lands, not before or after.”
- “Slide the foot; do not bounce up.”
- “Keep the hips at the same height through the step.”
Common Mistakes
- Punching before the foot lands, which leaves the punch unsupported.
- Rising up during the step, which telegraphs the movement and slows it.
