Setup
- Stand in a staggered boxing stance with feet shoulder-width apart and knees slightly bent.
- Bring both hands up to chin level in a guard position with elbows tucked close to your ribs.
- Distribute your weight on the balls of your feet to allow for quick, fluid rotation.
How to do it
- Drive one fist upward in a tight vertical arc, pivoting on the ball of the same-side foot and rotating your hips forward.
- Exhale forcefully with each strike, snapping the hand back to the guard position immediately after the peak of the movement.
- Alternate arms at maximum speed, ensuring the power is generated from the legs and core rotation.
- Maintain a rhythmic tempo, focusing on a 1-1-1-1 cadence for maximum speed.
Form checklist
- Keep your core braced and torso upright; avoid leaning forward into the punch.
- Ensure the punch stops at roughly chin height to maintain control and protect the shoulder joint.
- Keep the non-punching hand at your face to maintain a proper defensive guard.
- Pivot your heels and hips in sync with each punch to maximize rotational force.
Pro tips
- Focus on the 'snap' back to your face; the faster you retract the hand, the faster you can fire the next punch.
- Engage your lats and obliques to pull the punching shoulder back as the opposite arm fires to create a whip-like effect.
Make it harder
- Hold light 1-2lb dumbbells to add resistance while maintaining punching mechanics.
- Perform the movement from a static quarter-squat position to increase lower-body isometric tension.
