So today I was able to master FL/PE10. In two weeks, after deload I'll progress into FL/PE11. I took some time to check what was available on the gym, but I had no suitable place where I could do this exercise.
However, I've found by setting the rings just low enough that I can grab them with completely locked arms (no less, no more) with shoulders aligned under the rings I can do the body levers and they seem to be harder (but not absurdly harder) than the body lever with arms grabbing something behind my head. It also seems to hit the lats as I have to pull the rings down in order to have leverage for the exercise. It really feels like an assisted front lever which I think is the point of this progression.
Would this be acceptable for mastery of FL/PE11 and FL/PE12 ?
