CrossFit Santa Cruz L-Hell circa 2010.
We stress the importance of stabilizing the midline so often it may seem we are obsessed. Well... we are. The ability to hold a rigid midline may be the single most important factor in athletic development. Maintaining the L-sit for more than 1 minute is a realistic goal for most athletes. It may sound easy, but the L-sit is extremely challenging. Athletes with a 1 minute or longer L-sit rarely have issues with core strength. If you ever reach 3 minutes in a L-sit you have achieved something very special.
