not that i'm defending the decision, but joe said he's the most well conditioned athlete he's ever been around. he really doesn't look like he ever labors and so i'm sure there is truth behind this mentality, but it doesn't seem like it's necessary. Yeah but I'm not worried about him being gassed physically, I'm worried about his arm falling off. Can conditioning prevent that? (Serious question) the stronger your body is, the less taxation it has on your arm. It's not a total ultimatum, but it's certainly a factor. When your body (especially legs) get tired you rely more on your arm itself.
