Good Sparring/Gym Videos

It's always fun to watch a vid of top pros and prospects working out in the gym (next to being there of course)...Who knows maybe us "know it alls" can even learn something ;) ...I thought I'd kick it off with a a Pacquiao workout...Please feel free to add your favs....

Good stuff...I agree I like to see old footage of guys starting out as prospects etc and what they have become..Like Manny..

I still to this day get a Kick out of the Rocky scene with Duran....Who would have ever guessed what he would have become over time....
