Body-Solid SPRHT Hip Thruster Attachment The SPRHT is a padded platform that pins into a Body-Solid power rack and gives hip thrusts a proper home. Instead of dragging a bench over and hoping it stays put, you get a fixed, padded back support at the right height inside the cage. Why train hip thrusts in a rack? Loading and unloading. Setting the bar on the rack safeties between sets means you are not rolling a loaded barbell over your legs to get in and out. The U shaped 11 gauge steel frame keeps the platform from shifting under load. How long does it take to set up? Minutes. It ships fully assembled and mounts with easy grip pins, so you can pull it out and put it back between sessions. What does it fit? The Body-Solid GPR400, and the Pro ClubLine SPR250, SPR500 and SPR1000. Weight: about 31 lb. Size: 48 in. L x 8 in. W x 7 in. H.
