What is your motivation to get healthy?
Do you listen to music while working out?, if so, what kind of music gets you movin....
Usually epic music like old folklore and what not. Just look up epic music on YouTube or something. I do combat sports btw so I'm not sure if it would work for you but you should definitely try it.
