I read this article about Mike and his training routine was insane. He quite literally lived and breathed boxing, having Cus constantly monitor him and giving him feedback.
I feel like he is the perfect blueprint for fighters on how to hard to work and yet, I haven't seen anything like it since.
Here is the post if you guys are interested. If I had the time for it or if I was a pro, I would personally try to match or top this kind of work ethic.
Personally, I don't think we will ever see that kind of dominance and fear of a man in boxing again.
(despite what Wilder says )
