Instructions
Using a box, mount the rings with your palms facing inwards, keeping your arms straight and close to your body in a support position.
Bend your elbows and allow your body to slowly lower itself until the bend at your elbow just passes a 90-degree angle. Be sure to keep your arms close to your body at all times.
Hold this position for a second while keeping the rings steady.
Using your chest and triceps, drive your body back upwards until you reach the starting, support position.
