Begin by standing next to a single parallel bar. Jump up to the top position of the dip, then slowly lower yourself down with control, focusing on the eccentric (negative) phase of the movement. Lower your body until your elbow reaches approximately 90 degrees, or as far as you can comfortably manage while maintaining control. This exercise effectively targets the muscles involved in the transition phase of the muscle-up, helping to build strength and muscle control necessary for mastering the full movement.
