Excuse me but what in the world was that? Thank god he didn't do more than one set with that kinda form. I was awful and didn't remind bicep curl at all anymore.
That was just...well...unnecessary because he won't achieve anything by doing that.
I know that last set turned into a fucked up row rather the curl I'd wish the pro would stop trying to impress people with strength that isn't thier speciality it's looking good.
Leave the power to the umm i dunno powerlifters and strongmen.
