The L-sit is an isometric exercise that targets the core, hip flexors, and shoulders. It requires you to lift your body off the ground while maintaining a seated position with your legs extended.

  1. Sit on the floor with your legs straight in front of you.
  2. Place your hands on the floor beside your hips, fingers pointing forward.
  3. Press through your hands to lift your body off the ground.
  4. Keep your legs straight and parallel to the ground, forming an 'L' shape with your body.
  5. Hold the position for as long as possible, focusing on maintaining stability.

How to perform the L-sit

  1. Set up. Set up in a stable, balanced starting position appropriate for the L-sit using your body weight.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your triceps.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your triceps rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
