X⁴ was intentionally created to provide a holistic fitness option in a supportive group atmosphere. Unlike many group fitness gyms, X⁴ gives a consistent variety of anaerobic and aerobic training so athletes get a more well-rounded workout and never get bored.


Our Workouts

One of the main pillars of interval training is variety. In X⁴, you will rotate through four stations, each offering something new. While our stations remain the same, the movements performed and equipment used in each station varies daily in order to keep our members engaged and challenged.


Innovative Training

Weight icon



The Torpedo blends a barbell, a kettlebell and a dumbbell together into one, innovative tool. The Torpedo allows people of all fitness levels to press, pull, squat, swing, condition and build strength with unlimited variety. We use Torpedoes for movements like overhead press, weighted squats, deadlifts and more.

Cross RTR Workout Icon



TRX is a form of suspension training that uses body weight exercises to develop strength, balance, flexibility and core stability simultaneously. TRX straps can be used to accommodate all fitness levels and abilities. We use TRX Straps for movements like low rows, planks, lunges and more.

Heart rate icon



X⁴ utilizes interval training, meaning you will exercise at a very high work rate while performing movements that burn more calories both during and after your workout. There are four blocks during each class, Trueform, TRX, Strength and Capcity. The workouts change daily so you will never do the same workout twice!

Treadmill icon



TrueForm Runners are self-propelled and do not contain a motor. A TrueForm is the only running device that cues running form, as the belt reacts to every subtly in your movement, balance, posture, hip position, foot strike and more. We use TrueForm runners in every class, ensuring your running block changes daily to promote growth and change.

A Workout For Everyone

X⁴ draws people from all walks of life and fitness backgrounds. Everything can be scaled up or down, so each individual can perform his or her best.

Constant Variety

As we share some equipment with the CrossFit portion of our gym, we are able to constantly vary our movements. We will often replace a rower with a SkiErg, or a SkiErg with a bike in order to keep our members feeling challenged!


We always offer modifications to our movements. Whether you choose to run, jog or walk; whether your heart rate is in the red or blue zone; whether you’re lifting a heavy weight or using none at all, our coaches are here to cheer you on to the finish line and encourage you to meet your personal best, wherever that may be.

and Leaderboards

From time to time, we will hold challenges for our members. From a one-mile run or walk on the TrueForm, we are always showing our members their progress. For those on the competitive side, we keep track of a leaderboard for each challenge.

CrossFit + X⁴

X⁴ is offered solely at gyms also offering CrossFit. Some people view X⁴ as a precursor to CrossFit, while others view X⁴ as an additional training method or a totally new workout style unaffiliated with CrossFit. We offer separate and dual membership options so everyone can find the right balance for them.

We encourage our members to keep an open mind for both X⁴ and CrossFit.
