Setup
- Sit upright on the edge of a stable chair or flat bench with your feet flat on the floor, hip-width apart.
- Engage your core and maintain a tall, neutral spine with your chest lifted.
- Bring both fists up to chin height in a 'guard' position, keeping your elbows tucked close to your ribs.
How to do it
- Exhale as you punch one arm across your body toward the opposite side, rotating your torso so your shoulder follows the movement.
- Fully extend the arm without locking the elbow, rotating your wrist so your palm faces the floor at the end of the punch.
- Inhale as you pull the arm back to the starting guard position with control.
- 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.
