My buddy said he's been going old school and just doing a throwback workout. His exact words. "I'm doing quarters. The ol' 4x4x4" I just nodded and was like, "cool dude." I know that could mean a number of things depending on his interpretation, but if someone told you that's what they wanted you to do and you were afraid to ask what it meant (totally not what is happening to me) what would you do?
