Weight sled

A loaded steel sled pushed or dragged across turf

A low frame with a post for plates, pushed with the arms locked out or dragged behind on straps. Nothing lowers under load, so it drives the legs and lungs hard and leaves far less soreness the next day than squatting does. Gyms with a turf lane keep one; plastic versions work on grass. Weight, distance and rest are the only variables to set, which is part of why coaches hand it to beginners.
