Black Mountain Products resistance bands are made from the highest quality rubber to ensure maximum durability. This set includes five stackable resistance bands, two handles, door anchor, carrying bag, ankle strap, and exercise manual. This set provides the advantage of using any single or multiple (1-5) bands at once to achieve multiple levels of resistance. B.M.P.'s stackable set of exercise bands allow for a much wider range of resistance, (4 lbs. to 75 lbs.) than traditional bands sets. Any combination of bands may be used at one time, without the hassles of having multiple handles on each band. This increase in range and ease of use makes this set perfect for anyone from beginner to expert. Includes door anchor, ankle strap, and exercise chart.
