Setup

Boxing stance at jab-cross range from the bag.

Execution

  1. 1Throw the jab, retracting to guard immediately
  2. 2Fire the cross behind it with full hip and foot rotation
  3. 3Drive through the bag on both punches, don't just tap it
  4. 4Reset stance and repeat
  5. 5Move around the bag between combo sets rather than staying planted

Key cues

  • Jab snaps, cross drives
  • Both punches return to guard immediately
  • Turn the rear heel on the cross
  • Stay balanced — don't lunge into the bag
  • Exhale on both punches

Common faults

  • Throwing the cross before the jab fully retracts
  • No hip rotation on the cross
  • Standing too close and crowding the bag
  • Losing guard position after the combo
  • Static feet the entire round instead of moving

Tweaks

  • Add lateral movement between reps
  • Increase punch speed while maintaining form
  • Progress into 1-2-3 once grooved
