“Ultimate resisted speed sled- smooth and easy to transport. We used these during our preparation camp at Athletes' Performance Florida facility then we went back to our steel sleds and weight plates we have in Argentina and the difference was noticeable. I recommend these as the best sled to use.”

Build explosive leg drive out of the blocks with the SpeedSac. This variable weight sled allows you to strengthen your lower body muscles by resistance training similar to metal sleds. With removable weights, the SpeedSac allows you to adjust the towing resistance. You can also use the handles on the bags to perform various upper and lower body exercises such as lunges or front raises.
