Sergio Martinez is up there, multi sport athlete and has a varied training regimen and is a hell of a physical specimen i bet hes up there
A rugby league player only has a vo2max of around 50ml.kg.min, which is a level that can be easily developed in anybody (A sedentary person who is healthy usually has vo2max of 35-40ml.kg.min, never mind a professional athlete with a massive strength base). If NFL players weren't wearing protective equipment they would be getting killed on the field. Even with the protective equipment the force in a hit is over twice the force in a rugby hit. I find NFL boring as **** and I enjoy watching league so there's no bias here.
sure, take a look at the front five of any offensive line and the d tackle. Great athletes! :rofl Its 730 pm, time for beddie bye..:yep
