Lochte appears unstoppable as a physical specimen. the strength he illustrates in this video is almost incomprehensible for a swimmer. His unique dry-land regimen is featured here and his physique looks more akin to MMA/UFC fighter than your standard issue Olympic Swimmer.
I do question whether he is training like a sprinter rather than a middle distance specialist. Is his current muscle volume exceeding what is needed thereby creating more weight in the water than efficiency?
