If you live within 15-20 minutes of the Scottsdale Airpark, you've found your gym. I seriously love this place. The trainers are awesome, the workouts are balanced and thoughtful...different days, different muscle groups. They have group workouts/classes throughout the day, and some spin, boxing, stretch, and social events too. And some seriously nice and supportive people. Great clean locker rooms, fresh towels, a bottomless ice-machine -- which is an engineering wonder in and of itself -- the list goes on... I personally do much better with a structured class; and thought that my previous place was pushing me, until I got here. I'm 49 and stronger than I've ever been in my life. Infinity is a great gym, with great coaches. 'nuff said :)
