‘There’s no off-season for strength and conditioning coach John Allaire, who oversees the team’s off-season program. When testing players, Allaire said defensive backs and wide receivers typically have the lowest body-fat levels of all players. "Some are down to 4 percent," he said. "A typical NFL cornerback is somewhere around 8 to 10 percent. Four is low. Four, you’re talking body-builder type. I mean really ripped and lean, but we have those." A typical average American male’s body fat? "I’d say 20-23, somewhere in there," Allaire said.’
