  • Always evolving workouts. No one visit is the same.

  • 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.

  • 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!

  • Steve, Mark and Cassandra at the Rancho Cucamonga studio are terrific trainers. They cater to every body type. Patient and kind and alway there if you need help. They want you to succeed. I referred one of my coworkers to the Irvine 9 rounds. She then referred someone to the Chino Hills 9 rounds. I recently referred another coworker to the rancho Cucamonga 9 rounds. Her hours vary day to day and since there are no scheduled classes, 9 round fits her schedule day or evening. A great work out in 30 minutes. Thank you
