Mr. Bones doesn't actually have a waist, just a hollow space between his ribs and pelvis.

Remembering why you started your weight-loss journey can help lift your spirits when you’re down and motivate you to stick with it when you want to throw in the towel. “Take a moment each morning to remember what you’re working for—whether it be improved energy so you can play with your children or a longer happier life,” says Dyan Tsiumis, who dropped more than 70 pounds before becoming a personal trainer. “When you focus on all the good that will come from all of your hard work, it’s easier to stay on track,” she adds.
Even if you can't get to the gym, try to squeeze in a 30-minute walk daily, Lyons says. The simple boost in metabolism will help you burn waistline fat more efficiently.
