My back started aching when I watched the vid. But it does that any time I think about splitting wood. Just about anyway you do it, it is back breaking work. Lot's of lifting, stacking, ect unless you have one of the larger units that have the lift on one side, but you still have to stack it. It is a game for way younger people than myself. I just do enough for my shop stove, maybe a cord a year and some times will trade uncut wood for split and stacked.
