Start in an inverted hang on the bar or rings. Open your legs into a wide straddle position. While keeping your arms completely straight, slowly lower your body until you reach a horizontal position, and then continue until you are hanging vertically. Maintain a flat back and an engaged core throughout the entire range of motion. Focus on pushing the bar or rings down toward your hips to engage the lats. The goal is to control the descent as slowly and evenly as possible.
