Bench Reverse Crunch Circle
- Intermediate
- Compound
- Rep-based
- Waist
The Bench Reverse Crunch Circle is a dynamic core exercise that targets the lower abdominals and obliques by combining a vertical hip lift with a lateral rotational arc. Performing this on a bench provides a stable anchor point, allowing for greater pelvic control and increased tension throughout the entire core.

Setup
- Lie face-up on a flat bench, positioning your hips near the very end of the bench.
- Reach behind your head and firmly grip the edges of the bench to anchor your upper body.
- Extend your legs straight out in front of you, hovering them slightly above the level of the bench.
- Engage your core to press your lower back firmly into the bench surface.
How to do it
- Exhale as you pull your knees toward your chest, lifting your hips off the bench and driving your feet toward one side in a circular arc.
- At the top of the movement, rotate your pelvis across the midline to the opposite side.
- Inhale as you slowly lower your hips back to the bench and extend your legs back to the starting position, completing the bottom of the circle.
- Perform the next repetition by reversing the direction of the circle, alternating sides each time.
Form checklist
- Keep your shoulder blades and upper back glued to the bench at all times.
- Initiate the lift by tilting your pelvis, not by pulling with your arms.
- Maintain a slow, controlled tempo to eliminate momentum.
- Ensure your lower back does not arch excessively when legs are fully extended.
Pro tips
- Focus on 'scooping' your pelvis upward at the peak of the movement to maximize lower abdominal recruitment.
- Visualize drawing the largest circle possible with your knees to increase oblique activation through a full range of motion.
Make it harder
- Perform the entire circular motion with straight legs to increase the lever length and resistance.
- Slow down the eccentric (lowering) phase to a 3-second count to increase time under tension.
