Setup
- Stand in a standard boxing stance with your non-dominant foot forward and feet shoulder-width apart.
- Keep your knees slightly bent, weight on the balls of your feet, and hands up protecting your chin.
- Tuck your elbows into your ribs and keep your chin slightly down.
How to do it
- Jab: Snap your lead hand straight out, rotating your fist so the palm faces down, and exhale sharply.
- Cross: Pivot on your rear foot and rotate your hips to throw a straight punch with your rear hand, exhaling on impact.
- Left Hook: Pivot on your lead foot, bringing your lead arm up at a 90-degree angle parallel to the floor, and rotate your torso through the strike.
- Cross: Finish with a second powerful straight punch from the rear hand, then immediately snap back into your defensive stance.
Form checklist
- Keep the non-punching hand glued to your face for protection at all times.
- Ensure power comes from hip rotation and leg drive, not just the arms.
- Fully extend your arms on the Jab and Cross without locking the elbows.
- Keep your lead shoulder high during the hook to protect your chin.
Pro tips
- Focus on 'snapping' your punches back to your face faster than you threw them to improve hand speed and defense.
- Maintain a rhythmic exhale with every single punch to stabilize your core and prevent fatigue.
- Visualize hitting a target at eye level to ensure your punches don't dip or rise unnecessarily.
Make it harder
- Add a 'slip' or a 'roll' after the final Cross to incorporate defensive head movement and extra leg work.
- Hold light dumbbells (1-2 lbs) to increase the demand on the deltoids and improve punching endurance.
