Setup
- Grip the pull-up bar with an overhand (pronated) grip, hands slightly wider than shoulder-width apart.
- Hang with arms fully extended, engaging your lats and pulling your shoulder blades down and back to stabilize the torso.
- Bring your legs together and slightly bend your knees to approximately 90 degrees.
- Engage your core to eliminate any initial swinging or momentum.
How to do it
- Exhale as you pull your knees up toward one side of your chest, initiating the 'circle' by driving your knees laterally.
- Continue the circular motion by sweeping your knees across the top of the movement toward the opposite side of your chest.
- Inhale as you lower your knees back to the center starting position in a slow, controlled arc.
- Alternate the direction of the circle (clockwise then counter-clockwise) for each repetition to ensure balanced development.
Form checklist
- Keep your upper body as still as possible; do not swing the torso to create momentum.
- Maintain a 'hollow body' position at the bottom of the movement to keep the core engaged.
- Ensure your knees reach at least hip height at the peak of the circle for maximum abdominal recruitment.
- Avoid shrugging your shoulders; keep a strong 'active hang' throughout the set.
Pro tips
- Focus on 'tucking' your pelvis toward your belly button at the top of the circle to maximize lower ab activation.
- Imagine you are drawing a large, perfect circle with your kneecaps to ensure a full range of motion.
- Squeeze your legs together tightly to create full-body tension and improve stability.
Make it harder
- Straighten your legs completely (Hanging Leg Circles) to increase the lever length and difficulty.
- Slow down the tempo to a 3-second descent to increase time under tension and eccentric control.
