My dream: The un-gym

I went rollerskating this weekend, which I did last spring as well. It was so fun, and despite the sore muscles and bruises that resulted from a spectacular ass-over-teakettle spill I took, it was super fun. The only complication was that there were three birthday parties going on, and the place was teeming with kids of varying levels of comfort with or interest in the concept of rollerskating. So it was a bit like playing a real-life version of Frogger or Paperboy at times, which made things a bit nerve-wracking for those of us who aren't super skilled and have a higher center of gravity than the average eight-year-old.

The degree of fun I had while working up a sweat made me think, though, how awesome it would be if I could do this as a regular form of exercise. And that led me to think even bigger, and create in my mind a dream place to work out, which I'm calling "The Un-Gym."

The Un-Gym is based on the idea that adults are more likely to get fit if it's actually fun to do, and targeted at those who aren't comfortable with or interested in team sports. So here's the kind of stuff you'll find there instead:

1. Roller skating (grown-ups only, great '70s and '80s music, black lighting, and disco ball required)
2. Trapeze lessons
3. Playground equipment for grownups (adult-sized monkey bars, slides, swings, etc.)
4. Trampolines
5. Rock climbing
6. Anything else that's fun and non-competitive

Also, while memberships would be a cost-effective option for those who want to frequent the gym regularly, there would also be punch cards and individual day rates for those who just want to go once in awhile.

Finally, there would be a snack bar with food that's both healthy and fun. Smoothies with funky straws, whole wheat pizzas with star-shaped pepperoni, that sort of thing.

What would your dream fitness facility look like? Would something like the Un-Gym appeal to you?
