Take a pronated grip on the rings, hands shoulder width apart, and get into a push up position. Leg together, posterior pelvic tilt, core and glutes engaged.
Begin by letting the rings move slightly in front of your shoulders, and start bending your elbows.
Keep your hands in close, and descend so your elbows are fully flexed, maintain tension on your core and not allowing your back to arch.
(The deeper you descend, the greater the difficulty, adjust as appropriate)
Pause at the bottom, then drive the rings down, flexing your triceps and extend your arms, pushing yourself back to the top position.
