Set your rings to approximately hip height. Tie the resistance band to one ring, and loop it through the other, securing it by gripping the over the top of it.
Adjust the band so you remove the slack.
Begin with your arms straight, legs together and slightly in front. Bend your elbows and descend with control, as low as comfortable. Drive back up to the start and finish by turning the rings out and locking your arms. Repeat for repetitions.
