Looking at this video is why so many feel bodybuilding is a joke. How can anyone think that is hard training. I could get my grandma to do those quarter reps. Yes, Sergio did partials. He also did 400lbs clean and jerks when he weighed under 200lbs. Is there a top ten Olympia contestant that could do 300lbs? I will answer, no, not one. Most would have trouble with 250lbs. Sergio trained long and hard after working manual labor for 12 hours.
