Conditioning for advanced moves without weights?

There's two moves that I've been wanting and trying to get consistently, and I think some conditioning exercises might help me get there, but I wanted to ask for some advice about what I should do. The first is the aerial shoulder mount, which I get maybe 50-60% of the time I attempt it, but that's with me cheating the end by grabbing the pole with my ankle, and I'm a little worried about shaking the pole and injuring my shoulder when I do that. I attempt it 3-4 times a night, unless I think I'll be too tired. The second is the cup grip handspring. I tried this in class and was surprised and happy to find I like the feel so much better than twisted grip, so I really want to work towards getting this one solid. I'm much farther from this one - I haven't completed an attempt yet (without heavy help from a spot), just gotten my legs kind of up there and come back down. My teacher insists it wasn't a lack of strength so much as me consistently bailing on the move, but I would still feel more confident going into it with more strength. I know that weightlifting exercises would probably be ideal to build strength for these tricks, but I'm very hesitant to do that. I do personally dislike weights exercises, but the main reason I'm hesitant is because I already pole 4-5 days a week (1 class and 4 days of work), and I do a lot of upper-body-intensive tricks when I pole. I'm worried I would blow a fuse or something if I added weightlifting exercises to that O.o My body really needs the rest days I give it, especially with weight exercises. Is it a good idea for me to add anything to my week of intensive workout to condition for these tricks? Up until this point I had just built strength through pole itself, building up gradually to more and more advanced things, should I continue with that? Or maybe I should add a few conditioning exercises to the days I already pole? What should I add, if anything? I know I should target shoulders, lats, and obliques for the CG handspring (thanks Veena!), and I imagine mainly shoulders and abs for the aerial shoulder mount. Any advice would be appreciated :)
