Finally managed to do one and catch it on video. Things I need to work on (that I know): 1) more compression during the press, 2) keep toes pointed throughout, and 3) get more strength / do it slower. Right now I kind of "swing" during the first part rather than press.
I'm so happy that I at least have made it up to handstand. I've had the standing press on floor for a few months now, but this is my first time pressing from an L.
