Good for you!!!
Even making a small change always helps for the better. I can't afford a gym, but I like to walk...only the weather in Oregon during this time of year is very wet and cold. But my son loaned me his Wii game and I got the Wii Fit Plus for it. So even if I can't walk outside, I can still do a workout inside. It's a lot harder then I thought it would be and at the end of an hour, I've got a pretty good sweat going. HA Did not think at my age I would be working out to a Wii game....
I know you can do this, we all have bad days, but take a deep breath and start all over again the next morning and put the bad day behind you.
So tomorrow, plan on doing at least a 20 minute walk, just make yourself do it no matter what and then let me know how you did? I had to start out with only 15 minutes, that's how out of shape I was in....I've worked up to between 30 minutes and a hour each day now.
Don't forget to tell me how you did and be truthful....
