Weight / Fat loss

Ridiculous. That would have my max weight as 136 pounds/9.7 stone. I'd have zero muscle mass. I'll avoid that rule of thumb, thanks.

Alberto Contador: 5' 9.5" - 137lbs = 1.97
Chris Froome: 6' 1" - 152lbs = 2.08
Bradley Wiggins: 6' 3" - 150lbs = 2.00

*Wiki's figures

Seems about right. Of course your typical pro tour GC contender isn't exactly a typical human being.
