If you're a CrossFit or Hyrox fan, the chances are you'll have come across the fabled L-sit. An advanced calisthenics move (that's a blend of bodyweight strength and gymnastics, for the unintiated: think push ups, pistol squats and pull ups and you've got the gist), the L-sit can be performed seated on the floor with no equipment, on parallel bars in the gym, or even using kettlebells at home, too.
Done right, the L-sit looks effortless, but don't be fooled. The seated leg lift (as the move is also known) is a torchingly tough, full-body powerhouse move that will engage your arms, abs, hips, balance and stability like nothing else.
