Back, Core, Forearm, Latissimus
Set a pair of rings to be the same level as your head.
Grip the bar with a false grip - wrapping your hand the rings with your knuckles pointing to the ceiling. Aim to keep your arms shoulder-width apart.
Move your feet off the floor so you are hanging on to the rings.
Keep your arms straight, engage your body and core, squeeze your glutes. Don't bend arms throughout the exercise.
Hang for the required amount of time and them jump off onto the ground.
