That would fit the classical term for functional strength. Some guy's will only take if off a rack (like in the second video) and sit down on a bench, box, etc, pause a couple of seconds and come back up with the weight. That would be a dead stop off that bench, for example. Never seen any football linemen do that in regular (I, and guy's I trained with, never did) training, but I am sure there are somewhere. Great for serious strongman training (bolder stacking, etc), with the odd lifts that are required in a contest. Can also hit the abs strongly. Good Luck.
