I've heard a lot about Russell Simmons doing yoga. He's often mentioned with the roster of stars who once (and might still) practice at Jivamukti. He's hip hop's biggest yogi.
In a somewhat erratic interview, Lime.com presents Simmons explaining his practice. Watch him demonstrate sun salutations. He's got good form. But does he always practice with his shoes on?
