This YMCA location usually has the classes that interest me the most. I live close to the Windward Y, but I often go to the Nu'uanu Y because of the classes they offer.
Friendly staff and community, wide array of classes, for children and adults, clean facility, huge pool, and a nice variety of well kept exercise machines and workout equipment.
Great gym. Love the pool, though there needs to be more lanes available for adults for lap swim on weekends. It's hard to find time during the week to go, and the weekend is often the best time for working adults to swim there.
Exercise area is reasonably well maintained- I enjoy using recumbant bikes and weight trainig. I am concerned that some equipment has been down for more than a week without explanation of when it would be restored.
The programs, the large spaces and clean locker rooms. I also really enjoy the outdoor pool here! Its the reason that even though its a little further than the Y closest to me now, that I always prefer the Nuuanu YMCA.
