Exercise guide

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

  1. Lie face-up on a flat bench, positioning your hips near the very end of the bench.
  2. Reach behind your head and firmly grip the edges of the bench to anchor your upper body.
  3. Extend your legs straight out in front of you, hovering them slightly above the level of the bench.
  4. Engage your core to press your lower back firmly into the bench surface.

How to do it

  1. 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.
  2. At the top of the movement, rotate your pelvis across the midline to the opposite side.
  3. 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.
  4. 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.
