My biggest motivation is to not be like the rest of America. I use to weigh 260 and life just sucked now I bike about 30 miles a day require way less sleep and have such a high energy level my motivation is to not go back to what I use to be.
But when I need to kick start my motivation, I watch Rocky or Breaking Away thoughs two help get me wanting to go out and ride. Or read others success stories when I hear of others personel achievements it just gets me pscyhed and I want to go work out. Also changing routine helps alot I just like to go and find and see things that everyone else over looks. I also like to read articles on the benifits of working out, knowing I'm reduces my risk of so many health problems is motivation enough.
