Roelly Winklaar
Roelly Winklaar is widely considered to be one of the best of the younger generation of bodybuilders. Nicknamed “The Dutch Beast,” Roelly is only 5’6″ but he weighs a whopping 297 to 320 pounds. His upper arms are 24 inches, his thighs are 29 inches, and his neck is a full 19 inches.

Roelly’s best known for his large arms, which he says grow larger on their own. Winklaar claims that he doesn’t do anything special for his arms beyond his regular workout routine — they’re simply that big naturally.
