Cong Yan of Jilin, China weighed 230 pounds. He wanted to lose weight, but didn't know how. A weight loss business offered to help, but he couldn't afford it. So he found a simpler solution: wearing a 90-pound rock on his head.
Yan didn't start out that way, of course. He began 3 years ago with a 33-pound rock, then worked his way up to 90 pounds. Now he walks in a nearby park about 1.9 miles every day while wearing the rock. It works! Yan says that he lost 60 pounds in a single year. You can see more photos of him at the Daily Mail.
