Yep, and i think it's more like cm - 110 or 105 in reality when we talk contest ready ripped.
180cm = 70-75kg ripped.
Here's his more concise version, including a contest ready physique:
Furthermore, while 100 is a nice and round number, you'll obviously see some variance here as well. All things considered, a more precise formula for maximum muscular potential would look a little something like this:
(Height in cm) - 98-102 = kg body weight on competition day. Ripped and slightly dehydrated.
(Height in cm) - 96-100 = kg body weight. Ripped and under normal circumstances.
P.S. 180cm @ 75kg ripped is Spider-man's stats, so is Spider-man a lifetime natural?
