 Charis Cook

Owner and Head Coach

Charis is obsessed with the human body and biomechanics. She loves to help people learn about their bodies so they can move to feel, look, and perform their best. She is passionate about making pain-free movement, especially movement under load, accessible to everyone.


Most notably, she is certified in Russian Kettlebell (RKC Level 2) and comprehensive Pilates (BASI), both of which are pivotal parts of her unique coaching system. Having worked in rehab settings, she understands the importance of encouraging people to advocate for their own bodies when injured or going through any life transitions. As such, she is a certified Barbell Rehab coach and Functional Movement Systems (Level 2) coach, both of which connect her to qualified clinicians for referrals and collaboration. Of perhaps equal importance, she completed her training in nutrition from Precision Nutrition, which is considered the gold standard in the fitness industry. She is also certified through Kabuki Strength, TRX Suspension Trainer, and USA Powerlifting as a Club Coach.

"What a great spot. Great equipment and people, but most of all, great leadership. Charis is an incredibly strong woman who understands the mechanics of lifting better than anyone I've met. Her energy, fire, and attitude also make her extremely fun to train with and learn from. She pulls no punches, tells it like it is, and will help you on your fitness journey no matter what your goals are. Can't recommend this place enough."
