Functional fitness is training with a purpose. It has the ability to help you expand your physical literacy no matter what your goals are. We believe in consistently reinforcing foundational movements at relative intensity (as promoted by TBXMâ„¢ The Brand X Methodâ„¢). From a practical standpoint, functional fitness is learning how to move in your everyday life more efficiently. Squatting, pushing, pulling, lifting, climbing, crawling, jumping, and running are staple foundational movements in functional fitness.
