Mayweather is the Best Athlete Ever.

Steve Redgrave tops the list for me, and Pinsent should definately get a mention. Beyond that, Miguel Indurain takes the honours.

From Wikipedia:

"At the top of his career, Miguel Indurain had a physique that was not only superior when compared to average people, but also when compared to his fellow athletes. His blood circulation had the ability to circulate 7 litres of oxygen around his body per minute,[1] compared to the average amount of 3-4 litres of an ordinary person and the 5-6 litres of his fellow riders. Also, Indurain's lung capacity was 8 litres, compared to an average of 6 litres. In addition, Indurain's resting pulse was as low as 29 BPM, compared to a normal human's 60-80 bpm , which meant his heart would be less strained in the tough mountain stages.[2] His VO2 max was 88 ml/kg/min; in comparison, Lance Armstrong's was 82 ml/kg/min."

Still believed to be the lowest resting heart rate ever recorded - and think I remember reading somewhere that most humans would be technically dead that low.

 

Can't argue with this :good
