Rahmans trainer is bragging that hisfighter is sparring up to 12 rounds a few times

That is nothing! Really! Alot of fighters do their runs aqnd then just spar, anything up to 20 to 30 rounds in a day, obviously not all the rounds are very competetive.

I am amazed by some fighters training regimes, I read Tszyu only sparred something like 4 rounds a day!

I know Mike Tyson used to spar 15 fast paced rounds a day, thats the only way to stay sharp.

Toney also likes his sparring, if he has lost weight, under 220lbs then I see him winning.
