I just joined Mountainside Fitness (MF) oat the Arrowhead location with my BFF. So far my experience has been outstanding. Met with Brian in the personal training Dept for 1 hour consultation. He was very knowledgeable & we learned a lot about all components for a successful lifestyle change! Now I have visited their Carefree & I17 location since it's closer to my house - so if my BFF isn't working out I still go ... Just to Carefree location instead. The staff at both locations have been EXTREMELY friendly!!! Today I took M1 with Dana (Carefree) & she was incredible!!!! She also recommended another class to help with learning the moves to help me with M1 class. That class beat me today ... But I will be back!!! If you want to join a gym that COMPLETELY makes you comfortable going too no matter your weight / looks etc than join!!! Hopefully you tell them I referred you! See Ya There!
