l-sit on floor

Sit on the floor with your legs extended in front of you. Place your hands on the floor beside your hips, fingers pointing forward. Engage your core and lift your legs off the ground, keeping them straight. Try to bring your legs parallel to the floor, forming an 'L' shape with your body. Hold this position for as long as you can. Slowly lower your legs back down to the starting position. Repeat for the desired number of repetitions.
