PT in my commercial gym was "working out", running between a couple stations doing crossfit-type shenanigans, ending each circuit with a 135lb halfsquat (yes just one). Complete with a pussy pad, and for some reason, turned 90' from the rack to see himself in the side mirror.
The rack has a mirror in front of it.
He literally unracked the weight, walked out of the rack, turned 90 degrees, and did 1 halfrep.
He also left the weight on when he was done, and went on to coach a paying dummy.
