Setup

  1. Stand in a staggered boxing stance with feet shoulder-width apart and knees slightly bent.
  2. Bring both hands up to chin level in a guard position with elbows tucked close to your ribs.
  3. Distribute your weight on the balls of your feet to allow for quick, fluid rotation.

How to do it

  1. Drive one fist upward in a tight vertical arc, pivoting on the ball of the same-side foot and rotating your hips forward.
  2. Exhale forcefully with each strike, snapping the hand back to the guard position immediately after the peak of the movement.
  3. Alternate arms at maximum speed, ensuring the power is generated from the legs and core rotation.
  4. 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.
