This sounds a lot like the gym I go to. It's run by the hospital I work for, and most of the clients are a mix of hospital staff, older people from the community, and patients who wanted a low key place to get healthy. Some of the equipment counts calories, but there are no mirrors, and the staff are awesome. My dad, who is a one of the most dedicated yogis I know, took his first yoga class there after finishing cardiac rehab. Personally, I love it because health is stressed; not vanity, or snapping pics for Instagram.
