Active Release Technique, A.R.T., Is actually a combination of examination and treatment. Your Forever Fit personal trainer and ART provider uses their hands to evaluate the texture, tightness, and movement of muscles, fascia, tendons, ligaments, and nerves. Abnormal tissues are treated by combining precisely directed tension with very specific client movements. This patented, manual soft tissue treatment is effective for a broad range of soft tissue injuries for which most conventional treatments have failed.
