TESTIMONIALS

YOU'LL FEEL THIS ENERGY

The classes and instructors at CKS are AMAZING! I have been attending a variety of group fitness classes for over a decade, and the classes at CKS are my favorite! These classes will push you to your limit and provide you a great sweat! At CKS, it is truly only “you vs you”! Thank you, Crystallyn, for making your vision a reality and bringing this awesome studio to our community!

Morgan G

Crystallyn had a dream of CKS and she has worked hard to create an awesome workout community for everyone! She is so welcoming and makes sure you get a good sweat while being a great motivator throughout the workout when you are ready to be done. Bringing CKS to Sheldon has been amazing and has created a new community of people. Excited to see what the future holds for CKS with new instructors. So glad I said yes to going to hot yoga last May! It has changed my life for the better!

Lauren T.

I am so glad I found CKS. I was nervous to try it but I left my first class feeling amazing mentally and physically. The music is so upbeat and the instructors are very encouraging. The heat brings a different level of exercise and I love it!

Tracy W.

After many failed attempts at other gyms, finding CKS was one of the best things to happen in my life. Not only is it physically bettering me, but the community is simply unmatched. You become a family and have teachers who push you to do the best for you! Every class is different and challenges me after months of attending and can be modified for every body type and physical ability.

Kymlee K.

I just started attending classes and I am in love with the variety in the workouts, the upbeat classes, and the positive environment. I’ve tried a few different instructor’s classes and they are ALL great! This is by far the best workout class I have been a part of and something I look forward to each week!
