Setup
- Lie face-up on a flat bench with your head positioned at the very end.
- Reach back and firmly grip the edges of the bench or the support legs behind your head to anchor your upper body.
- Engage your lats and pull your shoulder blades down into the bench to create a stable base.
How to do it
- Inhale and brace your core, then swing your legs and hips upward until your body is nearly vertical, supported only by your upper back and shoulders.
- Exhale and slowly lower your entire body in a perfectly straight line from shoulders to toes, maintaining a rigid 'plank' position.
- Control the descent for a 3-4 second tempo, stopping just before your lower back or legs touch the bench.
- Pull your body back up to the vertical position or reset for the next repetition.
Form checklist
- Maintain a straight line from shoulders to heels; do not allow the hips to pike or the lower back to arch.
- Keep your glutes and quads squeezed tight to ensure the legs remain rigid throughout the movement.
- Ensure your weight stays on your upper back and shoulders, never on your neck or cervical spine.
- Keep a death-grip on the bench to prevent your torso from sliding.
Pro tips
- Think about 'pulling' the bench toward your head with your lats to create maximum upper-body tension.
- Focus on the eccentric (lowering) phase; this is where the majority of the strength and muscle gains occur.
- Imagine pushing your feet as far away from your head as possible to maximize the lever length and difficulty.
Make it harder
- Add a 2-3 second isometric hold at the lowest point of the movement, just inches above the bench.
- Perform the exercise on an incline bench with your head at the high end to increase the gravitational pull.
