This is what happens if you stubbornly try to lift a heavy weight and you don't have enough muscle and strength to do it. You can see how heavy the makeshift barbell is and how small his muscles are. Not to mention, his form is really terrible. You're not supposed to do a deadlift like that. You're supposed to bring most of the weight to your legs by pushing yourself against the ground while lifting the weights! He can even hurt his spine with that bad form!
