The MATrix Method™ Defined....

The MATrix Method™ brings the art of Pilates along with the athleticism and controlled movement of HIIT to the forefront. 

 **The word MATRIX is defined as:  “SOMETHING WITHIN OR FROM WHICH SOMETHING ELSE ORIGINATES, DEVELOPS OR TAKES FORM”  **The work MATrix is defined as: “ALL SYSTEMS GO”  and so The MATrix Method™ was created in 2019 by Kari Johns.  With the marriage of these two modalities,The MATrix Method™ is unlike any other 45 minutes you’ve given to yourself - but it will be one of the BEST!
