Marvin Hagler: “When I trained, I'd go away from everything. No women, no friends, no parties. I'd disappear. People thought I was crazy, but that's what it takes. “I called it going to jail. I'd lock myself up in Cape Cod and live like a prisoner. Run, eat, sleep, train, repeat. That was it. The day you start to like the lights, the fame, the cameras, you're finished. “That's when hunger leaves you. I stayed mean, stayed cold. Because in that ring, no one's your friend." Get locked in men!
