StringyBall is a squeeze ball on a string designed to stay attached to your wrist or palm to make exercising easier and a pleasant experience.
The main advantage of securing the ball is that it will not fall or roll away when doing exercises or during breaks; while allowing the user to do more complicated exercise maneuvers because of the certainty that the squeeze ball will not free itself. Just like conventional stress balls, StringyBall provides the same benefits with an added value of convenience.
