Hang from a pull-up bar with an overhand grip, shoulder-width apart. Engage your core, lift legs to a 90-degree angle (L-sit). Keep legs straight and parallel. Pull up until chin clears the bar, then lower slowly, maintaining the L-sit. Repeat.
Engage your core for the L-sit. Control movements to maximize muscle engagement and prevent injury. Practice leg raises if the L-sit is difficult. Keep shoulders down and back. Exhale on pull-up, inhale on descent. Start with fewer reps or use assistance bands as needed.
