This is a video I took myself at my gym. It has over 330,000 views on youtube.
This woman, if the treadmills to her left and right are free, would turn the other ones on too and hop from one to another. She also presses the up and down speed/incline buttons like she's conducting some sort of symphony. yeah, she's simply not all there.
Also not ice by the belt on her treadmill that she;s going dreadfully slow...I looked later and it was at about 1.8 kph, which is 1.1 mph.
