If you are having fun, it is less likely that you will notice how uncomfortable you are.
Running is fun for me...classes are not, so that wouldn't help. :)
I did, however, break down and buy a gabrialla support belt...and it makes all the difference in the world!!! Although I did more of a run/walk/run/walk, I could tell the second out the door that I wouldn't be in pain/uncomfortable like I am not using the belt, and I was able to run a bit faster than I had even been attempting to go without the belt since I'd been so uncomfortable.
Thanks for the input, ladies...I'm glad I got a support belt.
