It's true. Think about it.
I was walking by a gym and eating my ice cream when it hit me. The Gym is by far, the biggest and worst energy polluter of any industry.
Let's take a look at the building - It's a large building with air conditioning and equipment inside. The air conditioning must be able to cool hundreds of sweaty individuals, each one exhuming approximately 300 watts of energy. Hence, the AC must be sized to cool at least 9 kilowatts... that's above and beyond the building loads.
Then there's the equipment. Most of the people I see in there use a treadmill. These suck approximately 1200 watts of power. That's on top of the 300 watts exhumed by the human body. Then there's the amenities. The shower, the water, etc. They all use even more energy. Let's pin that at 1000 watts per hour per person.
So a typical person's one hour trip to the gym at it's most efficient uses maybe 2.5 kilowatts of power. And that's what you pay your gym membership for - the use of the equipment.
BUT it makes no sense! Why are we spending energy and money so that we can spend more energy and money? We go to the gym to burn calories - a form of energy. We burn this energy by consuming energy on the treadmill. So we can come to this formula:
Human energy consumption + Gym energy consumption = human energy spent + heat wasted + $$$ spent.
Something doesn't add up here. We're going to the gym and burning energy, but that energy is wasted by consuming more energy! It makes no sense whatsoever!
I have a proposal, however. Instead of spending money at the gym, we should trade that energy for cash / offset gym costs. Imagine if all the machines were hooked to a local power source which fed into the grid. Your contributions to the grid were measured using id tags so when you pop onto an exercise bike it will record your energy expenditures in terms of kilowatt/hours and refund your gym costs accordingly. Not only would you be able to reduce the electrical consumption of the gym, you'd be earning some money by doing so. The important part is that your energy is not wasted. Not turned into heat, but turned into a usable form of energy.
Let us all get together and say 'no' to the energy wasting gym! Until they do, I propose that we all boycott the gym and save our energy as stored fat until such a day as they realize the limitless potential of energy conversion!
Yes, this can work, an early example of such can be seen on a televised broadcast of gilligans island. The professor built a bicycle that could recharge the coconut batteries for the radio.
It's a hell of a plan. Except that people need to cycle a lot to generate a little energy (people have looked into this). But the fact that lots of people would be cycling might mean some actual savings.
I didn't make it!
Or you could just use the weights and bath in the local river.

I just exercise at home and use my own water. Gym's do serve a purpose, but I don't really use them at all.

Or you could just do what Ameircans do and go to Burger King, not much energy is needed.
Grabbing and holding the hamburger itself would require energy actually. =p
