The crescent circle is a basic core-strengthening move that targets the lower abs, hips, and lower back. The exercise also improves conditioning of the quads.
Instructions
Sit with your legs bent, feet flat on the floor. Lean back to rest your elbows on the floor. Place your palms on the ground and bring your knees into your chest.
Brace your abs and, keeping a straight spine and your thighs together, extend both legs parallel to the floor. Trace a circle in the air with your legs.
Trainer’s Tips
Focus on keeping your chest up tall and pulling your shoulders back.
Move through the exercise in a slow and controlled fashion.
