Re: weight lifting...why such different views on it in boxing???????
Check out Periodization training for athletes from T. Bumpa, this guys stuff is what everyone else is really copying IMO.
As for the stiffness, look at Pascal, he looks like a little Holyfield, and he has no conditioning, and I feel it has to do with the inordinate amount of Muscle tissue he has in upper body. Andre Berto too. Always fighting is spurts. Now compare that to Aaron Pryor or Joe Frazier, this guys bodies didn't look half as nice, but could throw punches for days. Henry Armstrong, Joe Louis... the list goes on and on
