Setup
- Stand with feet shoulder-width apart, then step your non-dominant foot forward into a staggered boxing stance.
- Distribute your weight evenly on the balls of your feet with a slight bend in your knees.
- Raise your hands to chin height with elbows tucked against your ribs and your chin slightly tucked.
- Align your lead shoulder toward your target, keeping your core braced and shoulders relaxed.
How to do it
- Snap your lead hand forward for the first jab, rotating your fist so the palm faces down at full extension, and exhale sharply.
- Quickly retract the lead hand halfway and immediately snap it out again for the second jab.
- Pivot on the ball of your rear foot, rotating your hips and torso forward to throw a straight cross with your dominant hand, exhaling on impact.
- Return both hands quickly to the starting guard position and reset your stance with a rhythmic tempo.
Form checklist
- Keep the non-punching hand glued to your cheek for protection at all times.
- Ensure the power for the cross comes from the hip rotation and rear foot pivot, not just the arm.
- Maintain a slight bend in the elbows at full extension to avoid joint hyperextension.
- Keep your core tight throughout the rotation to protect your lower back.
Pro tips
- Think of the two jabs as a distraction to set up the 'knockout' power of the cross.
- Exhale with every punch to maintain core tension and prevent fatigue.
- Focus on the 'snap'—retract your hand to your face faster than you threw it out.
Make it harder
- Switch your lead leg (Southpaw vs. Orthodox) every 5 repetitions to develop bilateral coordination.
- Hold light 1-2lb dumbbells to significantly increase the demand on your deltoids and core stabilizers.
