Building a better gym

Gyms and I don't gel well.

I like the idea of coming out from the gym - feeling lighter, more agile, and fresh from a shower. I just don't like the part of going to the gym, and the part where I need to actually exercise.

So its natural that I come up with ideas on why I don't like the place, and how we can do it better.

Idea 1 : Retrieve heat generated from the machines

The idea to make gym machines "green" by making them generate their own energy and also contribute to the grid has been coming up lately. However, electricity generation is a lossy process - any energy conversion other than heat will invariably be lossy. How about make the machines generate heat, then? Large gyms like the LA Fitness I go to now have hundreds of people taking showers through the day - if the gym can generate all the hot water it consumes, that's a lot of energy saved!

There are lots of places to head from that point - surplus hot water can be used to offer free laundry, at least for towels, making our gym bags a little lighter and giving us a straight motivation (a free hot towel, powered by our sweat, waiting after the workout)

Now, there were a few other ideas I had come across, but I forgot them all by the time I opened this browser window. Will update this post when I remember.

Wish there was a "green" way to revitalize my memory.
