I know that all weightlifting exercises are essentially pointless, but some seem especially pointless. Like this one: swinging a weight through about 6".
Having said that, I agree with Mike that it takes some strength to even get that off the ground.
230 strict press @ 220; bodyweight+187 X 4 dips @ 180; 403 front squat @ 210; 10 000 push-ups.
Ignoring irrelevant credentials since I was 17.
