WHY THEY WORK - Riff Bandz work for the same reason that swinging a weighted bat before stepping up to the plate works. Train with resistance, and when the resistance is removed the movement feels lighter and easier. Strengthen your fingers by using Riff Bandz resistance bands while you practice and play. | PROGRESSIVE STRENGTH TRAINING - Place the first Riff Band over your fingers. Warm up and play through your favorite scales, solos and songs. Increase the resistance by adding the second and third bands when you're ready. Remove the bands and feel your fingers fly down the fretboard or piano keys. Comes with 3 bands for increased resistance which can lead to increased strength and speed. | VERSATILE – Perfect for finger speed training for Bass, Guitar, Piano, Banjo, all stringed instruments, brass and woodwind. Increase your finger strength with this grip strength trainer. Any skill level can become a better musician faster with Riff BANDZ. | DESIGNED IN THE USA AND MADE WITH PREMIUM MATERIALS – Created and designed by professional musicians from the US.
