This video baffles me. Canadian arm-wrestling champ (225 lbs) easily beats strongman Hafthor Bjornsson (420 lbs). Bjornsson is the guy that plays the Mountain on game of thrones. Is the smaller Canadian guy actually just stronger, or is it all technique? [Of course, either one of these guys could rip my arm right off my torso, regardless]. Any TGP guys knowledgeable and/or good at arm-wrestling? Discuss.
