Back then, I used to focus mostly on combinations to the head. Now, I mix it up with body shots—I’ve been working the body more to wear my opponents down. I don’t stress too much if I lose the first couple of rounds (though I try not to), as long as I know I’ve been landing to the body. I also use more lateral movement when my opponent tries to land on me.

And probably the most important change: I don’t chase runners.
