The greatest motivator in the gym is not those who show up to exercise, yet those who's bodies are changing. There is much admiration and respect for those who step out of their comfort zones, test the limitations of their bodies, and change life as they know it to lose weight and gain health. 

Meet Jeff, via fitsugar, he's lost about 150 pounds by eating less, progressively lifting weights, challenging himself with cardio, and even coaches a bit of water aerobics along the way.

"Some days, I don't want to get up, but I say, 'You've got to get to that gym,' because I've seen how much I lost so far, and just [think about] what it's going to be like at the end of the rainbow," he says. "I want to get where I can live a long, healthy life and go places where I won't have any limitations."

So why aren't you in the gym?
