I had husband and wife both say they were going to the treadmill at the same time. The husband said to "Run" and the wife was going to "walk."

Hubby arrived first, stood on it and got it going and began running. Then wife climbed on and stood on the treadmill (while Hubby still running) and she began to set up to walk.

Once she got going, one was walking and one was running at the same time. It seems they do not realize someone else is using it at a different speed than they are.

I notice that only one at a time can use the hammock, but they do not seem to preclude more than one on the treadmill.

Is this a glitch? Watching one run while another walks at a slower speed at the same time is impossible to do in reality so?
