The Slastix Toner resistance band is a 48-inch, dual-handle resistance band. Using Stroops' patented safety sleeve elastic technology, this band supports every facet of your workout from warmups to arms, chest, shoulders, and legs. Stroops designs its resistance bands to have a long life and keep you exercising safely. Each Slastix band is wrapped in a fabric sleeve that protects it from cuts, scrapes, abrasions, and other forces like sun exposure, which quickly deteriorates naked tubing. The sleeve also prevents hyper-extension by maxing out before the band overextends, while stretching long enough to ensure you get the most out of your workout. Take it anywhere, whether you're warming up at the gym or wrapping it around a tree trunk and have the confidence that your band remains protected and long-lasting. The Slastix Toner is made to complement your workout to perfection, thus the dual-handle band makes it so that you can complete your exercises without having to rely on multiple products. To give you the best resistance for your needs and your fitness goals, this set offers 3 weight levels (Light, Medium, Heavy) of Slastix Toner resistance bands. The color of your handle strap is determined by the weight you choose and the color of your band. With Slastix's game-changing safety sleeve elastic technology, this toner will be essential to every part of your workout.
