Back extension roll (half or full)
Roll back to handstand
Roll to handstand
Most of the skills you see hanging around the hand support section of the code of points are still kicking because they were part of a compulsory routine back in the day, and such is the case for the back extension roll. Oh man, compulsory routines lurrved back extension rolls. If those making compulsory floor routines could have made the entire thing back extension rolls and a cartwheel to straddle jump, they would have.
The code has drawn the line somewhere, as the back extension roll now has to include at least a half turn to get credit as a skill, otherwise it’s just going to be viewed as a choreographic element.
