O ya well if some one is bragging to the word about how strong they are and then you see them fucking it all up. Ya let them know they are doing it wrong.
I see all kind sof shit from fucked up ROM to bouncing it off the chest type shit. If you are going to brag then do it right.
still some one doing a 150lb curl with one hand even if its not a full range of motion is pretty strong. Just holding 150lb in one had is not something the avg man can doo.
