A simple and beautiful move, but deceptively dangerous. This is one of the least awesome positions to fall in. Please make sure you have a spotter and safety mat until you feel fully confident. We prefer the cross-ankle version over cross-knee (although different body types may find cross-knee to be more secure), and encourage students to keep feet firmly locked together for safety rather than the more stylish both toes pointed.
We often enter the Layback from the Pole Sit -> Plank -> Straddle Back -> V-Sit combo, and we might follow it with Crescent or Iguana.
