I don't want to get into a gear debate here, but if you're talking about the Norwegian team you should be aware that they currently have one of the harshest drug policies for sports in the world, and that they are one of the nations in IPF that pushes even harder controls. Last year they had 122 tests of which 84 were in training and unannounced. To put it into perspective, IPF in US made 14 tests that year in total with one of them being unannounced.
Carl-Yngvar, the guy who made that squat, is also considered to have extreme genetics.
I can understand that you doubt it, but I believe that the Norwegian national team is drug-free.
