wakk0 - this is Campitelli and Wolf together here. We think you need to speak more russian in your everyday dialect. Russia is strong country; capitalist lifestyle makes you weak. Weak as a child. Compare to motherland, where even our seniors are strong as 9 month old piss, as evidenced here:
Start please to speak russian and type in cyrillic characters and see your puny shoulder issues subside. Пожалуйста.
All kidding aside, we don't see anything terribly wrong with your bench - there's a few tweaks we think could make it a bit better, though hard to tell due to the dark and poorly angled video, but nothing that would cause the kind of pain you're having. But obviously there's something wrong with your shoulder. Did you notice it doing anything else previously, or was this the first sign of a problem?
Yours in Revolution,
Comrades Wolf & Campitelli
