Trainer for developing gripping strength and power

摘要

A training device, including a ball and an anchored connecting structure that is anchored to the ball. A distal portion of the anchored connecting structure is a connector, extending from a distal portion of the ball, that is capable of connecting with a motion resisting device. A proximate portion of the anchored connecting structure extends into an inner volume of the ball, whereby resistance is provided to twisting and pulling motions between the anchored connecting structure and the ball, resulting from torsion and thrust loading during training.
