Setup

  1. Sit upright on the edge of a stable chair or flat bench with your feet flat on the floor, hip-width apart.
  2. Engage your core and maintain a tall, neutral spine with your chest lifted.
  3. Bring both fists up to chin height in a 'guard' position, keeping your elbows tucked close to your ribs.

How to do it

  1. Exhale as you punch one arm across your body toward the opposite side, rotating your torso so your shoulder follows the movement.
  2. Fully extend the arm without locking the elbow, rotating your wrist so your palm faces the floor at the end of the punch.
  3. Inhale as you pull the arm back to the starting guard position with control.
  4. Repeat the movement on the opposite side, alternating arms in a rhythmic, controlled tempo.

Form checklist

  • Keep your sit bones firmly planted on the chair; do not let your hips lift or shift.
  • Initiate the movement from your waist and upper back rather than just swinging your arms.
  • Maintain a tall posture throughout, avoiding any slouching or leaning forward as you punch.
  • Keep your feet pressed into the floor to provide a stable base for the rotation.

Pro tips

  • Focus on the 'snap' at the end of the punch by briefly squeezing your triceps and chest for maximum muscle activation.
  • Actively pull the non-punching elbow back as you extend the other arm to create more torque and engage the obliques.
  • Keep your core braced as if you are bracing for impact to ensure the abs are working throughout the entire set.

Make it harder

  • Hold light dumbbells or small water bottles in each hand to increase the resistance on the deltoids and triceps.
  • Increase the speed of the punches while maintaining strict form to turn the movement into a cardiovascular challenge.
