Pilates and a Lesson

I am over a year out and down -164, about 18 pounds from goal. I have been trying some new exercises and returned to Pilates which I had done at 412 pounds and even a few times on my way down (I am at 248 right now).   Here is what I learned.  After dinner last night I felt a terrible pain right where my new tummy probably is.  I had beef for dinner (I can eat filet from time to time) and was scared it got stuck.  I woke up this morning to a terrible realization.  I found pilates much more difficult and realized my muscles in my stomach area are extremely weak.  I figured that was just a product of the loss.  Now my entire tummy is sore and it is a muscle pain.  After reading up and talking to some people I realized that I was so heavy that I was doing it wrong all these times.  I can now do it right and that is why I am so sore. My wife has commented on my posture being a bit poorer since the loss.  This pain has made me realize how weak my stomach muscles are.  I am actually excited to see the results from this. Additionally, I lost a pound yesterday.  Anyone else use pilates?

I don't go to a studio, but I've been using Brooke Siler's The PIlates Body. Doing core work is definitely a help to posture and general health.  And yes, when you're starting out, the abs hurt a bit.  But if you do it regularly, it's tough to load them up enough to get sore.  

I tried it when I was six mths out and decied that I could not do it. Of the class I was i I was the only male and the only one who couldn't grasp some of the moves. felt like an idiot. Doug.
