I'm a big fan of varied workouts, doing different things as part of the event. I was reading about an exercise theory, (CST)
http://www.rmaxi.com/cst/, and they are all about full mobility, and applicable strength. They use indian clubs instead of kettle bells...
They talk a lot about core, and the strength of the physiology surrounding the muscle, including connective tissue, joints and the sheath of muscle that surrounds muscle(?).
I see a lot of common ground in some of the old school exercises which focused more on a movement than on a muscle.
