    Great class and great gym experience overall. Gym and locker room were very clean and great positive energy from the instructor and fellow participants. Highly recommend checking this F45 out!

    Really welcoming atmosphere, friendly and supportive employees, and a fun, high-power workout! This gym is well-run by very nice people and well-maintained. The classes are effective and always get me sweating, and there’s a nice sense of camaraderie as you’re paired with groups to move through the weight stations. The classes were quite full, but I was there in January during their bring-a-friend promo so that was probably as busy as it gets. They have lots of times throughout the day for classes so it works with any schedule, and the workouts are just under an hour and very effective. Lots of options for using weights so you can customize to your own level of difficulty.

    I’m new to the strength community and I can’t imagine there’s a better experience than what I’ve had the last year & 1/2 at F45 CB. Thanks to the owners, instructors and members for making this place so welcoming, inspiring and fun 👊 💪 🙏
