Working on my core and stretching

While the walking has been slow, the amount of time I have spent on it wasn't so bad.  I did get to use the pedometer which earned me an extra weight watchers points.  However, I have yet to exercise and work on my core and do some stretching my neck and my back.  I plan to stretch for 15 minutes and perform core exercises for another 15 minutes.  My core is something that needs strengthen since I often make comments about being an overweight diabetic.  With even the most minor exercise, that can change.
