GOOD: Eco-Gym

Chances are you go to the gym because it makes you feel good. But nothing kills that post-workout buzz like contemplating the environmental impact of traditional gyms—the air conditioning, the cardio machines, the thousands of tiny towels that are washed daily. Manuel de Arriba Ares has an alternative: all the exercise equipment in his gimnasio ecológico requires no electricity and is made entirely of recycled materials. At Ares' gym, reducing your impact is no sweat.
