By the end of the shoot [of Wrestler], my trainer was pushing me up three flights of stairs to my house and holding my arm like I was an old cripple. I had three MRIs in the first two months of working on the film. I felt like it really was over by the time we started shooting the movie.
I still work out most days. When I do it, I go full blast five or six days a week, two to three hours a day. I enjoy it. It's therapeutic for me.
I grew up in a gym in Miami, the one where Muhammad Ali trained. I had 142 amateur fights and lost three.
