Since I'm allowed to work with the silks during lyra practice time for straddle and ball, I think I might incorporate some of these into my practice. The straddle on silks is much like profile straddle on lyra.
I've been working on this, with my pullup bar at home. I also try to work on it during my hoop warmup, assuming I'm not at the pineville studio, with only the high hoop. I still don't feel brave enough to drop to an arm hang up there. If I can't get back up into the hoop, it's too far to drop down. (And it's really, super difficult to do toes to bar from the low hoop.)
Mine are about eye level now, with bent legs. But I found this video, to let me know I need to make sure not to let my head dip back. I have no idea if I'm doing that or not, I've never paid attention.
