Setup
- Lie flat on your back with your knees bent and feet flat on the floor, hip-width apart.
- Bring your hands up to your chin in a boxing 'guard' position with your elbows tucked in.
- Engage your core by pressing your lower back firmly into the floor.
How to do it
- Exhale as you curl your torso up toward your knees, keeping your chin slightly tucked to protect your neck.
- At the top of the movement, rotate your torso and throw a cross-body punch with your right arm toward the left, followed immediately by a left punch toward the right.
- Inhale as you slowly lower your torso back to the floor one vertebra at a time.
- Maintain a controlled 2-1-2 tempo: two seconds up, one second for punches, and two seconds down.
Form checklist
- Keep your feet glued to the floor; avoid letting them lift as you sit up.
- Rotate from your waist during the punches to maximize oblique engagement.
- Keep your hands near your face in the guard position between reps.
- Avoid using momentum or swinging your arms to pull yourself up.
Pro tips
- Fully extend your arm on the punch and turn your palm down at the end of the strike to better engage the triceps and serratus anterior.
- Focus on 'exhaling' sharply with each punch to create more intra-abdominal pressure and core stability.
Make it harder
- Hold a pair of light dumbbells (2-5 lbs) to increase the load on the shoulders and core.
- Perform the movement on a decline bench to increase the range of motion and resistance against gravity.
