I saw something similar to this on a runners thread, but I am not a runner LOL...
So I have been back on the wagon for about 2 weeks and with reasonable goals, excercise and eating correctly here is how I know things have changed for the better for me.
I no longer fear walking up steps. I actually think of it as a micro workout
I have little to no back and knee pain. Getting up and sitting down isn't an ordeal.
I don't have that stuffed bloated feeling I seemed to constantly walk around with.
I get excited when my newest Walk away the pounds DVD comes in the mail
I stop thinking walking 4 miles is not some type of torture tactic
I love sweating.
