X’s

Hang from a pull up bar with your core tight and legs lifted in front of you, parallel to the floor. Keeping your legs straight, open them out wide into a “V” shape, then bring them back together, crossing one leg over the other to form an “X.” Alternate which leg crosses on each rep. Keep the movement controlled and maintain tension through your core and hip flexors..

There’s a short video demonstrating this exercise on this page. For more resources to help your calisthenics journey, check out courses here.
