Sorry, but those Barbaccios are completely useless. I don't care what video they're on or what "pro" is doing them. People always try to get cute with deviating from your standard movements. Believe me, changing a small thing in your diet will yield much greater gains than mixing exercises and working on "powercore movements".
Why is it Coleman doesn't do these fancy abstract movements? Oh yeah, cause they don't fucking do anything but pull something.
