Fretting your way through "Bohemian Rhapsody?" Trying to tackle a Rachmaninoff sonata? Whether you're a guitar player, keyboardist, or computer keyboard artist, you could be contending with pain and stiffness in your hands that hampers your best performance. This reverse-grip hand exerciser is designed to compensate for the many gripping motions we do naturally every day. Strap it on to either hand (fits most), attach the individual tension bands to each finger and thumb, and you're ready for repetitive stretching that can help alleviate carpal tunnel and tendonitis symptoms and improve flexibility in your fingers. The design also features adjustable anchors for each band so you can customize the resistance for each finger. Plus, you'll look like a cyborg superhero in the process (sorry, web-shooting function not included). Made in New York.
