Short burst sprint training. Max output for 30 seconds, doing shuttles of about 20 feet in length. The starting position in a sprint uses a LOT of core, and with the short distance you never get out of the bent over position. Make sure you warm up if you try this though, or you'll pull hamstrings.

I toss these in a circuit once a week and it destroys my abs and back, makes me want to vomit, and causes my quads to seize. Fun times!
