There are a few things- Races are sure a good one for me as well! They keep me out training and I know that if I'm fueling my body with junk I'm not going to be able to run as long/fast/hard, so thats a big one for me, especially since I'm not trying to lose any more.
im3898 - theyre addicting arent they??
Fear is actually another one that keeps me motivated. Maybe its silly. My in-laws have more health problems than any family I've ever seen.. things like fatty liver, metabolic syndrome, aching joints/knee surgeries, tumors in the colon.... and mom and dad each tip the scales at over 300 lbs. They dont have energy to play with the grandkids, and getting up off of the couch is a struggle. I will do everything in my power to make sure that I don't suffer with the same problems that they do.
