Seated Legs Circle Over Bench
- Intermediate
- Compound
- Rep-based
- Waist
This intermediate core exercise targets the lower abdominals and obliques while requiring significant isometric quadriceps strength to keep the legs elevated. By using the bench as a height obstacle, it forces a larger range of motion and greater hip flexor engagement than standard leg circles.

Setup
- Sit on the floor facing the short end of a flat bench with your legs fully extended.
- Place your hands on the floor slightly behind your hips for support and lean your torso back at a 45-degree angle.
- Position your legs together on one side of the bench to prepare for the first arc.
How to do it
- Engage your core and lift both legs simultaneously in a large, controlled circular arc over the top of the bench.
- Exhale as your legs reach the highest point of the circle over the bench and inhale as they descend toward the floor on the opposite side.
- Without letting your heels touch the ground, immediately reverse the movement or continue the circle back to the starting side.
- Maintain a slow, deliberate tempo, focusing on keeping the legs straight and the chest lifted.
Form checklist
- Keep your legs squeezed together and knees locked out to maximize quad activation.
- Maintain a proud chest and avoid rounding your lower back as you lean away.
- Ensure the movement is driven by the core and hips rather than swinging the upper body for momentum.
- Keep your toes pointed throughout the entire set.
Pro tips
- Focus on 'scooping' your lower abdominals inward as your legs pass over the bench to maximize deep core recruitment.
- To increase oblique activation, emphasize the lateral distance your legs travel on the sides of the bench.
Make it harder
- Perform the movement with your hands lifted off the floor and held across your chest to remove the stability support.
- Hold a small dumbbell or medicine ball between your feet to increase the resistance on the hip flexors and abs.
