How to nail one of the hardest bbs exercises on the planet

You need to work your way up to this extreme core-scorcher

The L-sit is one of the greatest tests of overall core strength and stability, says Sean Garner, a trainer at Anatomy at 1220 in Miami Beach, Fla.

It’s so tough, you probably won’t be able to do it on your first try.

To pass the test in less time, Garner recommends working your way up to the L-sit with a series of progressively harder core exercises.

Your goal: Work up to a 60-second L-sit with your palms on the floor.
