"Trainer" tells his two clients that they're "doing back" today. Sets up a couple bars at 95lbs, and instructs them to grab the bar with mixed grip (he actually said "hook grip" but showed them mixed grip) bend over with it, do a row, and stand back up. Then says "50 times. Go!"
By the end, one of the guys was just flopping down into a round backed bent over position, and doing about a 3 inch ROM on his row while the "trainer" flirted with some girl.
