I heard that michael spinks used to train to failure for 2 minutes and rest for 2 minutes(or something like that) in an attempt to make his boxing as explosive as possible. Also something I noticed is that Tyson and Liston both bite their lips while jumping rope. Just some fun tidbits, got any more?
I can never forget the mental image of little James Green punching bubbles. This content is protected
I bite my lip when I jump rope because I am not very good at it so I fall down a lot and it hurts and I don't want to cry. My guess is that James Green punched tense and they had him punching bubbles to try and punch loose.
