I see this a lot in the gym. I call it Barbell Forrest. I imagine it is done for the sake of not having to lift the weight all the way from the floor before each set.
I have yet to catch the guy who sets all this up in action. He’s usually already moved on to the next energy-efficient workout.
When I finally track down this Green weightlifter by following his small carbon footprint, I’ll be sure to ask his logic of coming to the gym to work your muscles, then risk a broken toe to save themselves from doing extra work.
