The Gripmaster is a small device to train the muscles in your hand and forearm increasing your strength and dexterity.The device has individual springs for each of the four fingers in your hand excluding your thumb, since each finger is related to its own set of muscles and tendons the Grimaster ensures that all, or most of your muscles are trained.
The strength of each finger or the whole device can't be adjusted so the Gripmaster is sold in three versions offering different tensions, blue is the lightest, red medium and black the strongest.
After using the gripmaster for a while you will quickly notice a burn in your hand and forearm that means that your muscles are working, the less used to work the muscle is the sooner it will burn so with time you will be able to train for longer periods and evenatually increase your hand strength, this can be useful in several activities from sports such as golf or rock climbing to tennis and martial arts.
We found the device good to relax and discharge stress and it definitively works with your hand and arm muscles, the thumb not being used is a question mark about how the real improvementin your grip and a second criticism is that it is certainly boring to use it.

ReplyDeleteIt says either on the package or isnide or something, to work the thuimb you hook your index finger under the lipped side of the bottom and use your thumb with the closest spring section.
