The Dynamic Pup Sled is a great way to increase explosive power and acceleration for serious athletes at a great value. A complete lower body conditioning unit, the Compact Sled improves leg, hip, and core strength. Utilizing a fully-welded steel frame, our Compact Sled is lightweight in size, but a true heavyweight in the field, offering variable pulling resistance based on the amount of iron or Olympic bumper plates loaded on the 14″ plate post.
