Setup

  1. Assume a standard boxing stance with feet shoulder-width apart, lead foot forward, and knees slightly bent.
  2. Hold your hands up by your chin with elbows tucked in to protect your torso.
  3. Distribute your weight evenly on the balls of your feet to allow for quick rotation.

How to do it

  1. Cross: Rotate your rear hip and shoulder forward, extending your rear hand straight out while pivoting on your back foot; exhale sharply.
  2. Left Uppercut: Shift weight slightly to the lead leg, drop the lead hand slightly, and drive it upward in a tight arc using your legs and core.
  3. Cross: Immediately fire the rear hand again, rotating the hip forward to reset the momentum and maintain pressure.
  4. Left Hook: Pivot your lead foot and hip inward, swinging your lead arm horizontally at shoulder height with the elbow bent at 90 degrees.
  5. Reset: Quickly retract your hands to your face and return to your starting stance after the final strike.

Form checklist

  • Keep the non-punching hand glued to your cheek for protection at all times.
  • Pivot your feet and hips on every strike to generate power from the ground up.
  • Exhale with every punch to maintain core tension and rhythmic breathing.
  • Keep your chin tucked behind your lead shoulder during the strikes.

Pro tips

  • Focus on 'snapping' the punches by retracting your hand to your face faster than you threw it.
  • Maintain a loose, relaxed upper body until the moment of impact to maximize hand speed.
  • Ensure the hook's elbow is at the same height as the fist to maximize torque and protect the shoulder joint.

Make it harder

  • Add a defensive 'slip' or 'roll' immediately after the final hook to practice realistic combat transitions.
  • Hold light dumbbells (1-3 lbs) to significantly increase the demand on the deltoids and core stability.
