109.JPG Heres some pics of a sled that I made.This was my summer workout on the beach.Basically its just some pipe fittings and thick rope you can use chain as well.The reason its empty is for transporation to the beach to be loaded with sand.I have made one with concrete and eye bolts as the sled part connected with chains.These made with plastic would be better dragging on grass or sand if not they would wear out faster on asphault and concrete.Tires or metal would be better on those surfaces.
