The Spud Inc. Magic Carpet Sled is a heavy-duty weight sled designed for maximum versatility and portability. At less than 4 pounds, it’s considerably lighter than a traditional metal dragging sled, but gives up nothing in weight capacity—able to take on more than 600 pounds in steel plates. Use the Magic Carpet Sled on grass, Astroturf, carpet, or in any gym or training space with rubber or tile flooring. If it’s a non-abrasive surface, you’re good to go. When your weighted sled training is complete, simply roll up the Magic Carpet Sled and drop it back in your gym bag. For athletes at any level, this is a convenient, effective way to build the posterior chain and metabolic conditioning with one movement. Important: The Magic Carpet Sled should not be used on concrete, asphalt, or any rough textured surface. Speed sled training on such surfaces can cause irreparable damage to the sled. ** This product is not sold with the weight.
