A 54-year-old man from Jilin, China, claims he lost more than 60 pounds in 1 year by adhering to a bizarre fitness regimen, Shanghaiist reports. He began taking regular walks around the city while balancing a heavy cement block on his head.

Cong Yan, who’s about 5-foot-3-inches tall, became concerned about his weight four years ago. He tipped the scales at more than 250 pounds, and wanted to get healthier. Yan didn’t want to take diet pills to slim down, so he decided to try exercise instead. It’s unclear how Yan came up with the idea to add this unusual form of resistance training to his cardio, but today he credits it with helping him drop down to around 187 pounds.

At the beginning of his regime, Yan balanced a 33-pound block atop his head. As time went on, he gradually increased the weight to 88 pounds. Today, Yan walks daily, depending on the weather. He supplements his aerobic exercise with martial arts, climbing steps, and completing laps around the city’s bell tower.

People who have caught wind of Yan's routine are reportedly worried that the heavy block might harm his knees, head, and neck. However, Yan doesn't seem to be too worried about physical injuries. In fact, he hopes his walking routine will someday land him a Guinness World Record.

If Yan does end up getting a title, he'll be in good company: The famous book of achievements includes countless other fitness feats, including "Most People Lifted and Thrown in 2 Minutes," "Most Push-Ups Using Back of Hands in One Hour," and "Heaviest Aircraft Pulled by a Human."
