Dynamic Lifting Bands feature a layered band design that prevents the band from snapping all at once, but instead indicates wear by slowly shredding, thus preventing injury. Resistance bands are an extremely versatile component of any level workout program. The perfect accessory for resistance training tailored to the individual, Dynamic Lifting Bands enhance everything from suspension, mobility, pull-ups, squats, bench presses and more. Seven different colors for seven different resistance levels. Made from natural latex rubber of varying width and thickness per color.
