Well, I must say you guys have inspired me to do better.  Today, after a few weeks of trying to do pilates, I decided to bite the bullet and booked in a one on one hour introductory session.  I have just finished it and it's kind of a weird feeling.  First of all, what I was doing was on the right track but not right at the same time, if that makes sense!  I feel like I haven't really done anything but my body is feeling it.  Went through a variety of stretches and poses.  Really highlighted how tight, lacking in strength and flexibility my body actually is.  I am going to try to keep doing this at home 3-4 times a week.  I'm going back for a half hour session every fortnight as well.  Onwards!
