Setup

  1. Stand in a boxing stance with your left foot forward and right foot back, feet shoulder-width apart.
  2. Keep your knees slightly bent and hands up in a guard position near your chin.
  3. Distribute your weight slightly more toward the back foot to prepare for the drive.

How to do it

  1. Pivot on the ball of your right foot, turning your hip and shoulder forward simultaneously.
  2. Extend your right arm straight toward the target, rotating your wrist so the palm faces down at the point of impact.
  3. Exhale forcefully on the punch while keeping your left hand glued to your face for protection.
  4. Snap the right hand back to your chin immediately after extension while inhaling.

Form checklist

  • Rotate your rear hip fully forward to maximize reach and power.
  • Keep your chin tucked and your lead hand up to protect your jaw.
  • Ensure your rear heel lifts off the ground as you pivot.
  • Maintain a slight bend in the elbow at full extension to avoid joint hyperextension.

Pro tips

  • Focus on 'squashing the bug' with your back foot to ensure the power starts from your calves and glutes.
  • Drive your shoulder forward to add length to the punch and protect your chin.
  • Keep your core tight throughout the rotation to transfer energy efficiently from the floor to your fist.

Make it harder

  • Hold light dumbbells (1-2 lbs) to increase the demand on the deltoids and pectorals.
  • Incorporate a slip or a roll immediately after the punch to practice defensive transitions.
