i read that on all bodybuilding sites listing their stats....
...look at that:
and this is Arnold in his prime, ALSO said to have a 34 inch waist size.
There is a huge difference. In the 2 first pics you can see the "celltech gut" starting to protrude.
Look how much the bones on the left and right of the lower abs have thickened on the influence of HGH.
There is no way they have anywhere under 38 inch waist size. They are massive but large waists pretty much ruins a bodybuilder's body esthetically.
