I have been going to SSF for nearly 6 years! This is a private gym with great facility and excellent trainers. You will get the best result and stay fit all through the work out routine. They also train high school athletes for baseball and football programs. Very spacious and always get to use the equipment you want, not wait and never crowded. Just a great gym with awesome people. Membership only. They also have dietary programs with high quality supplements.
I highly recommend Scottsdale School of Fitness for those who want to maintain a healthy and active life!
