Fitness Replacement Parts (FRP) is the leader in aftermarket replacement resistance bands, also called weight straps. Our unique bone style bands were designed to replace OEM Soloflex and many Body by Jake bands. FRP recommends buying bone style bands in pairs or sets to assure equal lifting resistance on each side of your workout. This set includes four total bands: (4) 10lb and (4) 25lb bands, for 1400lbs of total resistance. Made from heavy duty vulcanized rubber for extended life span! Each band has a reinforced attachment area. Buy with confidence as we provide a 1-year product defect warranty; if the band fails for any reason we will replace it at no cost to the original buyer.
