Set the rings so they are just above hip height. Grip them with your palms facing each other, and jump up into he support position.
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.
While holding this position, move your hands inwards until rings touch. Keep your form while doing this. Then return to previous position.
Repeat for the required amount of repetitions. Don't allow any bend in your elbows.
