Black Mountain Products resistance bands are made from the highest quality rubber to ensure maximum durability. The Ultimate set includes seven stackable resistance bands, two sets of handles, two door anchors, two ankle straps, carrying bag, and exercise manual. This set of exercise bands provides the advantage of using any single or multiple (1-7) bands at once to achieve multiple levels of resistance. The Ultimate Set allows for a much wider range of resistance than traditional sets. Any combination of bands may be used at one time, without the hassles of having multiple handles on each band. All products ship in "Certified Frustration-Free Packaging."
