So far this is my favorite gym in Arizona. It's variety of locations are convenient and the dollar amount on the membership is right on point with the packed value that the gym brings. What's most important to me at a gym is the vibe and environment, and the people it attracts. This gym attracts and promotes greatness. The motivational posters on the wall down to the types of equipment and classes range from the hardcore and bad ass too the serene and chill for recovery. I had an incredible consultation with Will Taylor at the Scottsdale pavilions location, he helped adjust some flexibility on me and now I feel like I have an upgraded body awareness. He also recommended a trainer exactly for my goals and put the first session on the house since it's those specialties are beyond his scope of practice. Very professional. Very friendly, very knowledgeable. Thanks mountainside. The only upgrade I would like to see is actually the music they play. Could be more motivational and have harder beats/songs, better variety instead of just top 20 hits. Would like to hear more metal, dubstep, EDM, rap, workout music instead of club music (:. One more thing GET BIGGER TIRES and REAL tires!!
