• Tesi FORZA Hand Exerciser and Strengthener


    The Tesi FORZA is a rubber hand strengthener that works your extensor muscles. You know, the ones that OPEN the hand.

    Like the jaws of an alligator, these muscles are frequently ignored. We focus on grip strength. 

    But do you know that half of the movement in playing a musical instrument is lifting your finger? Giving your extensor muscles a good workout can build strength, agility and speed.

    The Tesi FORZA is available in three tensions to meet your hand-fitness needs.  The rubber is flexible enough to be able to fit most fingers.
