 Trustindex verifies that the original source of the review is Google. Love this place! Been coming here for 2 months after trying out their trial period. Didn’t have a ton of gym experience before coming here, but everyone was very welcoming. Lots of class times, so it’s easy to find something that works for you, and having so many coaches around is really helpful. They’re always willing to answer questions and make sure you feel supported. 10/10 recommend

 Trustindex verifies that the original source of the review is Google. SISU Fitness is a fantastic gym! The facilities are clean with high quality equipment. The best part of SISU are the people. The coaches are caring, encouraging and really put a great effort to take an individualized approach to everyone while also creating a fun, inclusive and spirited environment for all athletes in 1:1 and group classes. The results physically and emotionally you will see are the proof points. I would 100% recommend SISU.
