Used by Professional and Amateur musicians, FingerWeights increase speed, dexterity, endurance, and control for all players – all instruments. Designed specifically for musicians, the slip-on model fits comfortably on any size finger and is worn during practice and pre-performance warm-up. FingerWeights target the extensor and flexor muscles, the tiny muscles that open and close the fingers. The extensors (speed muscles) determine how quickly the musician can move from one key or string to the next. The flexors close the fingers and are essential for purity of tone.
The Musician is a unique form of athlete. Whether driven by string or wind, FingerWeights are guaranteed to improve your playing.
