Setup
- Sit tall on the edge of a sturdy chair or bench with your feet planted firmly on the floor, hip-width apart.
- Engage your core and pull your shoulder blades back to maintain a neutral spine.
- Bring both fists up to chin level in a defensive 'guard' position with elbows tucked close to your ribs.
How to do it
- Rotate your torso slightly and drive one fist upward in a 'scooping' motion, aiming for an imaginary target at eye level.
- Exhale sharply during the punch, rotating your palm to face toward you at the peak of the movement.
- Inhale as you return the hand to the starting guard position under control.
- Immediately repeat the movement with the opposite arm, alternating sides in a rhythmic tempo.
Form checklist
- Keep your glutes glued to the chair; do not let your hips lift as you rotate.
- Ensure the movement starts from the core and obliques rather than just swinging the arm.
- Maintain a proud chest and avoid slouching or rounding the lower back.
- Keep the non-punching hand at your chin to maintain a proper guard and balance.
Pro tips
- Focus on a 'snap' at the top of the punch by briefly tensing your bicep and chest to maximize muscle fiber recruitment.
- Visualize punching through a target to increase the intensity of the concentric phase.
Make it harder
- Increase the speed of the punches to a high-intensity interval pace while maintaining full range of motion.
- Hold light dumbbells or weighted gloves to increase the resistance on the deltoids and biceps.
