Q:

What kind of muscle workout was Mike Tyson was doing?

I'm looking for the details of the muscle workouts that Mike Tyson was doing when he was training. 
I need to know what muscle groups he was concentrating on, and what workouts he was doing for those muscles, and the routine of these workouts. Daily scheduling would be nice as well.

A:

From what I've gathered in various interviews, it looked a bit like this. He would have huge peaks when he was getting ready for a big fight. This is what he reported doing daily, his average training time coming in at 55 hours per week.

Run 4 miles.
Walk 10 miles.
> 2,000 (decline) sit ups.
> 500 push-ups. 
> 500 shrugs with a 30 kg barbell 

He would do his run, eat breakfast, and fall back asleep. Then he'd spend the rest of the day doing calisthenics, sparring, bag work, and eating.
Most of Tyson's training was at the hands of Cus D'Amato, and you can read up more on the training plans he had for his fighters.
