  • I love everything about 9 Rounds! The trainers are knowledgeable, friendly..you always have that one on one training when you need it. I have a back injury and they are easily able to come up with a modified move that's just as intense w/out straining my back. Everyday the workout is entirely different. Every workout you will spar with a trainer on one of the 9 rounds. Soo much fun! I've worked out a long time and this by far is the most fun yet intense workout in 30 minutes I've ever experienced.

  • Always evolving workouts. No one visit is the same.
    - Jan 17, 2019 by Drew Forester
  • The trainers are absolutely incredible! They take the time to get to know you, where you are at physically, and what you are looking to accomplish. Then they spend each session guiding you to ensure you have a safe and productive workout. It is also very reasonably priced considering you essentially have your own personal trainer every time you workout and you can workout as often as you like.
    - Jan 10, 2019 by Christine Brown
  • I can go in whenever I'm able to since there are no set class times. I never get bored with the workouts because they're always changing. The staff is friendly and great to work with.

  • 9 Round is the best gym I have ever been to! I am treated like like family by the owners; Steve & Micki, & the trainers; Mark & Casandra. There are 9 stations: 1 abs, 2 weights/cardio, & 6 bags. Each station is 3 min long with 30 second exercises in between each station. Everyday 1 station is replaced with freestyle; a trainer works 1:1 with me on the pads. That is my favorite!. It is so invigorating!. 9 Round is the perfect workout. It's quick-30 minutes, hi- energy, full of variety-the activities at the stations change daily, personalized-a trainer is always with me and it is so much fun!. This the perfect workout for a busy teacher like me!
