The sport of bodybuilding has changed dramatically from the days of Arnold Schwartznager. Generation Iron has been taking fans and viewers through the experience and giving viewers and consumers a first-hand look. Now, the franchise is working on a third installment, "Generation Iron 3."

Edwin Mejia Jr. is the producer and Vlad Yudin director of "Generation Iron 3". The pair joins Cheddar to explain how this film will be different.

"Generation Iron 3" takes the fans internationally to see the sport around the world including in China and India.

The pair answer the question of what it takes to be a bodybuilder today. Mejia says it is more than just being able to pick up heavy things. He says that the successful bodybuilders are smart, humorous, and have charisma. It is also a lot about what you eat and when you eat.
