The Ring Muscle Up Eccentric is a controlled exercise focusing on the downward phase of the muscle-up movement. Begin by getting into the top position of a ring muscle-up, with your arms fully extended and your body above the rings. Slowly lower yourself down, maintaining control throughout the descent. Keep your core engaged and your body straight as you transition from the dip position to the pull-up position, and finally to a dead hang. This exercise helps in building strength and control necessary for the full muscle-up.
