I've always wanted to do a pole class, they run them at the local dance centre here, but i can't fit another sport into 7days of the week.
Re the sweaty question, i've been thinking about this over the summer. I'm now pretty fit as a result of road riding and running, and i sweat a lot more now than when i thought i was fit.
In my early 20s (before i took up mtb'ing) i was a gym bunny, and thought an hours cardio plus weights meant i was fit. I didn't sweat a bit on the treadmill in the gym, etc. When i started riding, i realised i wasn't outdoors fit, or very fit at all! Over the years, I've been training harder, and I sweat a lot more. An hours run can leave me soaked from sweat – especially in the summer – and during a 45min spinning class, the sweat will run down my arms because I'm working hard. There's other women in the class who are totally dry during and after the class. I think its to do with how fit you are – the fitter you are, the more efficient your body is and the more you sweat to cool your core down. Or at least, that seems to be my experience of it anyway.
Either that or at age 30, I'm starting the menopause!
If you are stressed/anxious, that can also make you sweat more. Plus, during the time of the month, our core temp is hotter than at other times of the month, so you'll probably sweat more then.
I think a lot of women just don't work very hard at sport, and therefore don't sweat.
