Eminem Once Lost 81 Pounds By Running 17 Miles Every Single Day

Rapper Eminem's 17-miles-a-day running regimen is a cautionary tale for young athletes.

If you want a perfect example of obsessively working out, it's Eminem's almost unbelievable story detailing how and why he used to run every single day.

If you've followed Em's career, you probably noticed that in the late 2000s, right around the time he released his album Relapse, he looked awfully skinny. Sickly, even. That's because he was.

The rapper, whose real name is Marshall Mathers, had been battling a pill addiction during which his weight ballooned to 230 pounds. After getting clean in rehab, Mathers said his "addict's brain" needed something else to grab on to. Wanting to lose the extra weight he had gained, Mathers chose running. What happened next borders on insanity.

"I became a hamster—17 miles a day on a treadmill. I would get up in the morning, and before I went to the studio, I would run eight and a half miles in about an hour. Then I'd come home and run another eight and a half," Mathers told Men's Journal. "I started getting OCD about the calories, making sure I burned 2,000 every day. In the end, I got down to about 149 pounds. I ran to the point where I started to get injured. All the constant pounding from the running began to tear up my hip flexors."

Eventually, Mathers scaled it back down. He now combines cardio with programs like Insanity and P90X. Lesson learned. The hard way.
