Through the end of March, ripped trainer Lisa Gaylord gets medieval on your ass for no charge, pushing your limits via plyometric jump squats on top of tractor tires, furious sledgehammer/tire smashing sessions, and dreaded tire flipping. On Fridays there's a DJ, and at the end of class, free healthy grub and beer, a deal that finally responds to your "will flip tires for beer" cardboard sign.
