★ 5★ 4★ 3★ 2★ 1Core Havn is my new favorite place! If I could go daily I would, but my muscles need a break:) One of the best workouts I’ve ever done, it’s challenging but in the best ways. Each instructor is so encouraging and I appreciate the way they watch you and correct to avoid injuries. I leave class feeling lighter (literally:), encouraged, and with the mentality that I can do hard things :) If you want a place where the people are kind, the studio is gorgeous and the workouts produce results, Core Haven is your place! I cannot recommend this studio enough! Thank you so much:)
April 27 · lauren mullenI am relatively newer to pilates, but have had a lot of experience with fitness classes over the past 20+ years. A few months ago, I tried my first class at Core Havn and was so impressed that I signed up for a full membership and the classes have become a fundamental part of my routine. The owner Cat has done an incredible job not only creating a beautiful and spotless studio space, but also maintaining the highest standards for her instructors. There are a lot of class options, and so I find I can get into classes easily, but I have also been pleasantly surprised that the instructors are consistently excellent. It’s fun to see how each instructor has his/her own style and preferred routines. The instructors are conscious of the varying experience and fitness levels of the participants and I feel that they create a welcoming environment for everyone. They are very conscientious about teaching proper form and cuing micro adjustments to avert injury and so that you can get the most out of your practice and challenge yourself safely. I had previously had a sort of dichotomy in my head of workouts that are fun vs. workouts that are good for me (e.g., yoga, mobility work, stretching, etc.), but I find the classes to be so enjoyable that I look forward to them, but also come out feeling as though I’ve had PT.

April 02 · Anne GThis is hands down the best workout I’ve ever done! Classes are small and feel like a good community. Every time I leave the studio I feel stronger and taller. Thank you Core Havn for giving me a safe space to workout in.
June 23 · Chelsea RyeNot an official lagree studio but they use a similar machine and moves. Definitely cater to the moms of MI so the classes and spring loads are not as intense or difficult as studios in LA or NYC. Great intimate class size though and you can always advance any move. I do wish we were in moves for longer times but that’s just subjective. I love coming to this studio when I’m back home on the island! Would love to see a 60min or advanced class too.
May 17 · Kelsey YinJose at Core Havn is the absolute best trainer! I always look forward to my personal training sessions with him and after over a year of consistent 2x a week sessions, I can confidently say I am the strongest and most toned I’ve been in 15 years.
