This reminds me of the startup idea generator that spat out "airbnb for workouts". My reaction to the basic idea is the same I had for a startup I saw on Shark Tank (I think), which was airbnb for pools. And that reaction is: ewwww, no thanks.

I just can't imagine ever using such a thing. Of course, I'm not a gym user in general so take my opinion with a grain of salt.
