Whos been the most consistant well conditioned heavyweight ever?

[Southpaw Stinger]

Definatly Marciano, no contest.

[aljon]

Something I was just thinking about for a minute.Marciano comes to my mind first.I never put a ton of thought into it or did any kind of research,but he comes to mind as a guy(heavyweight) who has alway came into every fight physically ready.

It's gotta be Larry Holmes IMO...
