  • I like that it's a complete, full body workout in only 30 minutes! I also like that the activities change daily so it's a little bit different each time I go.
    - October 04, 2018 by R.J.
  • Each experience is a bit different. Always surprised by how much I still need to improve, as we work out areas not usually conditioned. Coaches are great and make sure you do your best. It's like having a personal coach at a really reasonable rate.

  • I love that I can go in any time of the day and have an awesome workout. Each day is a different routine, targeting different muscle groups. The trainers are the best- able to encourage, explain, and suggest modifications or challenges. I feel stronger, physically and mentally, after a session!

  • The thing I like the best is that it’s like having a personal trainer. They are always there to make sure you are doing everything correctly.
    - September 14, 2018 by C.H.
  • Friendly and motivating staff. Ramin, Jordan, and Montana are just great at working with you on your goals, and respect everybody's ability, adjusting to what works for each individual. They show you how to do each exercise correctly, make sure you do not injure yourself, and challenge you. I would highly recommend the RSM location to all my friends that would like to get fit and have fun while they are doing it.

  • I like that you always have a trainer working with you that is keeping an eye on you, correcting when you are not doing an exercise correct, so you won't injure yourself. They are also very motivating without being insulting, they are very encouraging, always acknowledging your effort, which really makes you try and push yourself just a little more. I never been to big on gym type workout, but I love this. In just a short time I have more energy, more endurance, and the close fit better too. Thanks team!
