....i wonder what type of stuff they have on the inside of this gym....haha

I wonder if they have moving walkways inside like in airports.

This looks like a photoshop to me.

I've seen this photo several times before. But it always manages to get a chuckle from me, too. But then again, you could actually work out a lot on those escalators by going up the down escalator, and down the up escalator... several times.
