The Green Microgym Belmont offers its members a green gym with a friendly, community feel. We are located right in your neighborhood, so you can bike or walk here. The most unique thing about our gym is that the actual energy of the members helps power the building. It makes pretty good sense. You don’t need a ton of energy-sucking machines to get a good workout. We are machines. You power your workout. The energy bar one member just ate powers the ceiling fan for the next three hours.
