The Russian.

In fairness, I don't know if Vladimir is Russian or not. He was my workout partner last night at boxing and although I may be faster, should he catch me, he'd knock my block off. I should explain - Vladimir is about 6'5", practices karate and although he's lanky he's tremendously strong. His bodyshots strike the heavy bag at my headlevel. We had a really tough workout - and I'm really feeling it today.
