I’ve been coming to this gym for years and truly can’t say enough good things about it! I love the variety of workouts, especially Pilates and cross training. The classes are always challenging in the best way, and the instructors do such a great job of keeping you motivated while making everyone feel welcome, no matter your fitness level. I also appreciate the wide variety of class times.
What has kept me coming back for years is the community. It’s such a positive, encouraging environment, and you can tell the coaches genuinely care about the people who walk through the doors. I always leave feeling stronger, accomplished, and glad I showed up. Highly recommend Core!!
Great gym with great coaches. My wife loves working out here as well. What really makes this place great though is the childcare which keeps me coming back in without excuses!
Love this gym! I’ve been going here for a few years. There’s a great sense of community, and I’ve met some really great people here. Always a welcoming atmosphere—highly recommend!
I can’t say enough good things about Core Fitness! From day one, the community atmosphere has been so welcoming and supportive. The class sizes are small, which means the trainers can actually focus on your form and give expert, personalized guidance throughout the workout. The trainers are incredibly skilled and passionate about what they do. On top of all that, having a reliable, high-quality childcare option makes getting my workout in totally stress-free. It’s truly a gem of a studio!
Core Fitness Modesto is the best cross training gym in Modesto with Pilates and Barre classes. Each class gets me out of my comfort zone and presents unique challenges. The instructors are excellent, making sure everyone has perfect form while making sure that modifications can be made for those who have certain physical issues. I’ve been going there for 2 1/2 years. I am highly impressed.
