We have a family membership for about a decade now. This location is proximal and we like the fact that it's clean and well maintained. The trainers are generally courteous and knowledgeable and the place is usually busy at the height of the day.
The pool is also busy and so are the various classes. Restroom facilities are also clean and nicely kept stocked etc. the basketball gym and racquetball courts are nice if you want to loosen up after working yourself into a tight knot, so to speak.
About 15 minutes from the Bell/53rd Ave. location is the new PHXBC indoor badminton place where we like to loosen up in a world class setting with the sporty version of a well known popular game. Highly recommended as well for fitness/fun.
If you lug kids along, LAF also has a day care that might be suitable to keep the 'Chillies' engaged for a bit. Enjoy and stay in shape!
