PalmGard Edge Weighted Training Gloves (Pair) Increase your power to hit harder and throw faster. Edge Power™ Gloves were first developed to strengthen a third baseman's arm and increase the velocity of the throw; they worked! Shortly after that they were tried as a training device to increase bat speed. Again, they worked, and they continue to work over and over again. Players at all levels of the game benefit from these training gloves and they are the only training device that increase strength while the wearer is doing nothing more than throwing or batting.

This is known as functional strengthening exercise.
