There no doubting that Dr. Dre has gotten VERY diesel over the years. The hip-hop mogul has been taking good care of himself and fortunately, his hard work has influenced old school rapper, Warren G.

In 2007, Warren G was featured on Celebrity Fit Club and admitted he let himself slide after the show. He said he discovered a new sense of inspiration after a conversation with Dr. Dre.  Warren G tells TMZ: “A lot of people in my family have high blood pressure…Dr. Dre told me I better start hitting the gym, so I took his advice.”
