Vault - I don’t really vault anymore :-( but when I did I was working on the springboard entry up to a FHS on a pile of stacked mats. I could make that setup at my current gym, but dragging so many giant mats around on my own doesn’t appeal!
Bars - lol a pullover. It’s just never really happened for me, it’s still very inconsistent. Getting closer, though! I hope to have it solidly by the end of this year. I find hip circles, under swings, jump to HB etc infinitely easier...
Beam - cartwheel is taking a while to get consistent, but it’s not “hard” per se. I think making fluid connections is hardest for me.
Floor - working on front tuck at the moment. One day I’d like to learn a back tuck. I can’t do backwards hands-down tumbling because I discovered the hard way that my shoulders really don’t like that kind of pressure, but sometime it’d be cool to get RO - BT. I have a pretty powerful RO so I hope it’s doable. I also hope to connect FHS - FT, in the future, as well!
