LEILA FADEL, HOST:
Good morning. I'm Leila Fadel.
A man in Spain secured his 57th Guinness World Record over the weekend. Christian Rodriguez is what you call a serial world-record breaker. He's currently the fastest man to have done 100-meter sprint backwards, in a sack and blindfolded. His latest one - running in 2-3/4-inch stilettos. Rodriguez said his training was exhaustive and specific. That's also how I approach walking in heels.
