Eminem Opens Up About Addiction, Losing 80 Pounds and Getting Healthy

The rapper said that his addiction to pills caused stomach issues.

In no time, Eminem, 42, was running seventeen miles a day on treadmill -- half before work, and half after. The rapper, whose real name is Marshall Mathers, became obsessive about burning 2,000 calories every day and dropped to about 149 pounds. However, he also hurt his hip flexors, and realized he needed to mix things up a bit.

"I tried out some of those workout DVDs you do at home. One of the first ones was Shaun T's Insanity workout. I know a lot of these DVD guys are wacky, but I'm alone in my gym; I need someone on the TV yelling to motivate me," he said. "Besides, some of this s*** is entertaining."

Mathers began mixing in other workout DVDs too, including the P90X, which he still uses for abs, and the Body Beast, which he does every day instead of running. Now, before he heads to the studio, he does the DVD workout with free weights, a bench and a pull-up bar.
