     “As a former champion, Arnold has inside knowledge of the inner workings of the athlete“

Arnold invented “Thenar Glove” a patented revolutionary compression and resistant glove system that functionally strengthens the hand simultaneously using all fingers, allowing isolating functional movements for superior strengthening of the finger, hand, wrist, and forearm. Thenar technology, resistance in each finger with functional movement, has three distinct strength levels. Thenar has been used to restore strength to the surgically repaired hand of Olympic gold medalist Paul Hamm for the 2008 Olympics. It has also been used by the Fairfax county police department, US Marine Corps, NFL team, professional baseball players (MLB ), professional basketball (NBA), United States professional tennis Association (USPTA) , mixed martial artist (MMA), and professional boxing. It has also been used for non-sports, occupational and non-occupational, diabetic neuropathy, stroke persons paraplegia, quadriplegia, and in the hair industry. Arnold has successfully eliminated RSI (repetitive stress injury) for individuals in leading industries, served as guest speaker on health fitness finger hand strength performance for teaching tennis professionals at the USPTA Eastern annual convention.

Arnold developed the “Arnold Principle,“ a method and system of functional sequenced stretching of the finger ,hand ,wrist and forearm to improve performance and eliminate and prevent injury.

Arnold Tobin‘s belief is that “ We are born equal , our lifestyle creates imbalance.“ His system of balance, repetition, and consistency is the heart of Thenar and is both the external and inner “Source of Strength.“
