Class Offerings:

(45min) An essential and defining element of the overall Crux fitness programming. Focussing on improving range of motion (ROM) and then building strength in that newly acquired ROM. A fantastic class in which to learn self assessment tools, everyday mobility self care, and to positively effect every movement you make every day for the rest of your life. No big deal. Climbers, you should be in here. All levels recommended.

(60min) 10-15m warm up of mobility, dynamic stretching, and cardio. 45 minutes of movement using various styles of Circuit Training in an effort to engage the body and mind, improve agility, balance, strength and endurance, maintain an elevated heart rate, and generally bomb-proof the body. You will be carefully instructed in the use of dumbbells, kettlebells, medicine balls, battle ropes, and steps/boxes amongst other functional training tools. All levels welcome!

(30min) Just what it sounds like, a short format class designed to focus on two highly requested areas of the body. Drop in and strengthen the core, the back, and the back end to improve power, posture, injury prevention AND frankly to look good coming and going. Just keeping it real. All levels.

(60min) This class is a balance of the major muscular movements of pulling, pushing, squatting, and pressing with a focus on strength, endurance, and a bit of cardio added in to round it out.  A great class for those looking to concentrate on foundational/traditional weight lifting movements and accessory work.  Ground control fo major gains.  All Levels.

Flowletics is Tatiana’s signature calisthenic movement system that uses your body weight and the floor as an apparatus. You will warm up incorporating strength and mobility drills that target necessary ranges for the ensuing class patterns. Calesthenic body weight movements target strength through full range of motion that will also support your body in other activities.  Expect to have fun and tone up. Side effects: develop coordination, strength, fluidity, and dopeness.

Wear socks, pants and t-shirts!

CRUX Fitness Program Mission

Our mission for the Crux Fitness program is to use a variety of systems and techniques to create better human movement, minimize injury, and improve both physical and psychological confidence.

Our bodies are born with the genetic belief that we will be running, squatting, climbing, and digging; however, our lives tend to lack those movements due to being stuck in chairs, desks, cars, and repetitive movements. We then go to a gym for an hour to mimic what our body should be doing during our waking hours. This programming is specifically designed to maximize that gym time and get humans moving better with regards to what our bodies were actually designed to do.

Personal Training

If you are looking for more personalized training for specific goals or specific athletic needs, please email our Fitness Manager, Audrey Davis, and she will happily connect you to the trainer that best fits your goals!
