What boxers outside the normally mentioned Ali/Roy Jones types were unbelievably gifted athletes? Wilfred Benetiz comes to mind, lack of training and all. Mike Weaver claimed he never lifted weights a day in his life. Strange for a guy with the nick name of "Hercules". In that vein, Norton said he never did anything behind simple bodyweight/medicine ball exercises. Some pshyique, regardless. Who else?
Willie Pep? Heard somewhere on hear that he hardly trained yet he would make most peoples top 10 p4p of all-time post-war.
Athletically, Mike Tyson was terribly strong from a young age - whatever the validity of the rumor of him benching 300lbs when 16, it merits a sharp eye brow raise. Typically, all great boxers are great athletes. With them sporting great power, speed, strength and co-ordination their muscle fibers are usually pretty in tune to cardiovascular strains.
