Practice yoga, not dead lifts.

Think of a bull rider and you'd be forgiven for envisioning hulking, denim-clad dudes with forearms like Popeye. In reality though a better comparison might be a jockey. "You don't see any really big guys because if you get off-tilt and need to pull yourself back to the middle, it's that much more weight. Chris Shivers, one of the best guys who's ever done it, is like five-four, 140 pounds. He looked like a bump on a pickle but he could ride really well." And height aside, hulking muscles are less a factor than agility. In fact, the the five-foot-nine, 150-pounder says instead he practices yoga to improve his core and balance. "None of us are trying to get really big and bulky because we're never gonna out-muscle the bull. We're just trying to be quick, explosive."
