I know I'll get used to the Frog Stand eventually. My thing is with the "Bent Arm Half Straddle Planche Hold". This is my second attempt at this (Tuesday was my first attempt). As I read through 2 forums so far, I received additional advice on how to get the Mobility workout going with 2 forms of substitutions. Shown below in the videos (2nd half of each, first half is the Frog Stand). Also during the second attempt I noticed I was able to push up from it (guessing because I had a wider grip).
