I joined a pilates class today.  (the yoga classes are only offered during the times I am in class.)  Wow I couldnt  do it all but i did a lot of it.  I also walked for ten minutes before the class.  I think this is a good routine for me it is a lot of strengthing and I really like the instructer!  i am going to try to attend 2 or 3 times a week!  Good luck to me!LOL!  My chest still hurts but since the heart doctor has cleared me than I am just going to take it slow and keep working at it!
