The function itself is a simple concept. Ankle mobility is one of the largest limiting factors in the training of high level athletes, and has carryover from peak performance to posture, injury prevention and everyday healthy living. The TESS device is thoughtfully designed, and easily implemented into our training prep work. The piece can be intuitively engaged, easily adjusted, and provides the practical and useable features that make athletes who have used it, gravitate towards it as part of their routine. I am not aware of any other device that encourages the consistent and correct daily usage that yields noticeable and measurable progress in the useable mobility, strength and suppleness of the lower extremity.
