Interesting that you say boxers, because he spent a lot of time studying Muhammid Ali, watching film, etc. He liked boxing more than most martial artists and tried to incorperate some of the striking techniques.
Any guy that can drive his fingers thru an unopened Coke can, do pushups on his thumbs, or explode a 100 lb punching bag with a kick is pretty jacked.
"Bruce was incredibly strong for his size. He could take a 75-pound barbell and, from a standing position with the barbell held flush against his chest, he could slowly stick his arms out straight out, lock them and hold the barbell there for 20 seconds - that's pretty damn good for a guy who at the time weighed only 138 pounds! I know 200-pound weightlifters who can't do that!"
"Bruce had a big heavy bag hanging out on this patio. It weighed 300 pounds. I could hardly move it at all. Bruce said to me 'Hey, wally, watch this!' and this monster of a heavy bag went up to the ceiling - thump! - and came back down. I still can't believe the power that guy had."
I buy into the baddest man alive thing.....
