Re: How to force myself to like exercising
You know, you won't have to lose 80 pounds just to get to the point where DDR is fun again. If you manage to shed, say, 10% of your body weight, you'll find it's substantially easier to get around and do things. You'll also build a little muscle.
One thing that might help is "useful" physical activity. Instead of going for a walk just to go for a walk, go for a walk TO someplace. When you run errands, go for a more distant parking space. Or, if you have a yard, do some yard work.
