I built a wooden dummy with a PVC body, which is bolted to a base. It is pretty good and functional. Only problem I have: figuring out how to weight the thing down! Right now, the only thing I am doing is placing dumbbells on the base. It is currently weighted down with 270 lbs. I myself weigh 215, so I thought exceeding my weight would help, but nope! The base still lifts off the ground when I hit it. Any ideas on a better way to weight this thing down?
