Set the rings so they are slightly below hip height. Grip them with your palms facing each other, and position yourself in a support position while your legs are bent a bit and assisting you.
Arms should be straight, triceps engaged & shoulder depressed away from the ears.
Rotate the rings outward, so your palms are facing forward. Legs together, and feet slightly in front, so you can keep your core braced.
Hold this position for time. Don't allow any bend in your elbows.
