Look around the turf, and you’ll probably find a sled (or a prowler, which is a type of sled). You can push or pull these, so let’s look at a few variations.
One good place to start is a backwards sled drag. Find a pair of handles (they may be made of rope, strapping, or chain). Face the sled, and step backwards to pull it across the turf. These are amazing for the quads.
