Does anyone practise ashtanga yoga or Bikram yoga? I have been attending a fairly generic but lovely council-run class for a year, and also did a Ruth White weekend, and now am looking for another class or at least a one-day workshop to cover the summer holiday period. I have tried looking on the internet for London workshops and wondered about ashtanga or Bikram, to try something different. Why are these styles so trendy? Is it just fashion, or do they tend to attract a younger crowd? Some of the classes look a bit scarily strenuous, although I am quite fit. Also, are the ashtanga or Bikram classes full of intimidating sweaty men (although my yoga teacher (we only ever get one man in our class who looks well over 50) was joking that if you should go to ashtanga if you want to meet men - and that would be a plus!).
