Dan John says carrying The Slosh Pipe, which weighs in at a mere 38 pounds, is like wrestling a python, will totally kick your ass, etc. It'd be hard to believe, if it weren't coming from such a good source. Gotta build me one of those. Sounds like fun.
And as long as we're on the subject of fringe (but likely killer) core exercises, check out the picture on the cover of the October CrossFit Journal, and consider this description:
Gymnastics coach Phil Savage explains how to use a simple bucket-and-rope contraption to allow the Rest of Us to train like gymnasts. Working the ability to perform circles on the floor (as male gymnasts do in competition on the pommel horse) with the feet supported and rotating around the body provides excellent strength and coordination work that carries over to all sorts of endeavors.
I bet a few circuits of Slosh Pipe carries and Bucket Circles would be just the right kind of torture.
