I just finished the bent leg hollow rocks which I found excruciating. However, I find the straddle hollow body hold much, much easier. I was not going to move on from the bent leg hollow rocks, but I did seeing as I have no problem with the holds.
Similarly, I found the parallel bar negative dips fairly tough. While the parallel bar dips I find quite easy. I could knock out the mastery level of these before I began. I don't know where I'll go with the dips at this point.
Any thoughts or suggestions? Thank you!
