Emily,
It is funny, I can do all the hard stuff like crow, and side crow and all the koudinyasanas, strength is not my issue. I am SO tight in my hips and hamstrings. Partly genetic and partly from running and cycling. So the 85 degree classes really help with my flexibility.

So like sitting in staff pose, awful. Sitting with a wide leg straddle awful. Chataranga....easy peasy.
