Well, the market is already saturated with those, so it is assumed that there can't be any more aerobic gyms that are profitable.
Besides, this will at least be fun, and I can claim that through my advertising it will convince people that my way of gym is better or something like that.
Thanks for the help so far, kinda confirmed my ideas of having power racks, kegs, tires, kettlebells.
Would anyone think that a four lane 100m track would be a good idea? 2 lanes of rubber, 2 lanes of turf? Use it for sled drags maybe? Maybe a larger turf area to do agility stuff. Any other ideas in what would draw you to a place like here? Certain things in the locker rooms, on the stereo, or whatever?
