Movement: Begin by hanging from the rings and bracing through your core. Now bring the rings in front of you by shifting your weight and your hips, keeping your arms straight. From this position, raise your legs out in front and to the sides until they are parallel to the floor. Contract your abdominals and surrounding muscles while minimizing flexion in your lumbar spine. Lower your legs under control and repeat. Keep your arms straight and shoulder blades stable throughout the exercise.
