Okay.... call it "I am that stupid" or... "should have paid attention during physics/engineering class"
Yesterday I was busting out a metcon, and on the second rep of pull ups, I tore the bar out of the lam beam.
It was a near disaster, buy I escaped with a minor bruise (and a failed workout).
I guess 2" screws on flanges are not sufficient to hold a 175.... 185 pound man in a kipping pull up.
I call it bad ass, but most would call it stupid engineering.
Thought I would share.
