Hey :).
Don't give crossfit up if you enjoy it. I don't know much about it, but in the long run it could build strength in a different way to pole that you could use to your advantage. If it's the fact that it's making you too sore to pole that's making you want to quit, then like all things, eventually, I'm sure your body will becoming accustomed to the new workout and you won't be as sore. It's just probably using different muscles that you're not completely used to using.
My regime. well, I can't pole during winter because I only have an outside pole since finishing uni and I can no longer afford pole dancing lessons now that I'm not a part of a university pole dancing society. And so I use the winter months to go to the gym, build stamina and muscle, do workout DVDs like p90x and insanity, and increase my flexibility. As soon as it starts warming up (which is now beginning [unfortunately I currently work 7 days a week and have no time to even put my x-stage up in the garden]) I pole a few times a week when ever I have enough spare time to get a good few hour session in. On days when I won't have the time to pole, I get in flexi training, I go to the gym less in the summer time due to using that time to pole, but I do go maybe once or twice to use the weights. I have no dance experience, apart for doing a few things while at school. I have two left feet and look awkward as hell attempting any type of dance move. I generally avoid that aspect of pole, which I probably shouldn't, but I know there's no helping my two left feet so I focus mainly on tricks, spins and a few arm movements that don't look too bad. Anything involving moving my feet, hands and hips at the same time doesn't really work with me. Unless I'm upside down :P.
That's pretty much it, give or take.
Maybe don't focus too much on a routine and just do whatever you're feeling like doing that day. Maybe pole, maybe some weight training, maybe just flexi training or include it after a workout. Do what makes you happy. :) xxx
