Setup

  1. Stand with feet wider than shoulder-width apart, knees slightly bent, and hands in a 'guard' position near your chin.
  2. Position your body in a slight stagger, with one foot slightly ahead of the other.
  3. Keep your weight distributed on the balls of your feet for quick movement.

How to do it

  1. Inhale and lower your hips into a squat, moving your head in a 'U' shape as if ducking under an obstacle.
  2. Exhale and drive upward, rotating your torso to throw a straight punch with your lead arm.
  3. Immediately duck again, then rise and throw a punch with the rear arm, pivoting your back foot to engage the hip.
  4. Maintain a steady, rhythmic tempo, alternating the punching arm after every duck.

Form checklist

  • Keep your chest up and eyes forward during the duck; do not round your lower back.
  • Fully extend your arm on the punch without locking the elbow to protect the joint.
  • Pivot your hips and feet to generate power from the ground up rather than just the shoulder.
  • Keep the non-punching hand tucked against your jaw for protection and balance.

Pro tips

  • Imagine your head is tracing the bottom of a circle during the duck to maximize oblique and quad engagement.
  • Squeeze your glutes at the top of the movement to stabilize your base before the punch connects.

Make it harder

  • Hold light dumbbells (1-3 lbs) to increase the demand on the deltoids, pectorals, and triceps.
  • Increase the depth of the squat and the speed of the transitions to turn it into a high-intensity cardiovascular movement.
