A couple coaches have mentioned that my DD (L2-3) has exceptional strength but needs work on flexibility. Just curious if that is typical? From a physiological standpoint it makes sense. She's got that shorter, thicker body type and very defined thigh and calf muscles. Not that it matters....she's having a blast and I'm sure she'll get her flexibility too. Being a nurse I just seem to ponder these things . By the way, our first 2 hour class went very well. In usual fashion, on the way home, she informed me of how many days until she could go back. I swear she would live there if they rented out rooms!
