I Want the Perfect Body II by MTV Networks

Rebecca is 24 years old and is pursuing her Ph. D in Neuroscience at Harvard--a self-described "lab geek." To prepare for a fitness competition, she needs to build serious muscle tone and decrease body fat, while still maintaining her femininity for the swimsuit round. Things are coming along with her fitness training until she pulls her hamstring. In order to rest her injury, Rebecca pulls out of the South Beach show, but two months afterward competes and places 7th of 10 competitors at the show in Chicago. She graduated from Harvard with a Masters and plans to compete again.
Ryan is 23 years old, five-feet-three-inches tall, and weighs 105lbs. His goal is to become not only the leading jockey in Maryland again, but also one of the top five jockeys in the nation. By achieving that, he hopes to earn a mount at this year's Preakness, one of the biggest days in horseracing. To accomplish these goals, Ryan needs to gain weight. However, if jockeys weigh more than 112lbs they're not allowed to ride. By working out and trying to eat more than two small meals a day to gain weight, he runs the risk of getting too big and not being able to ride. Ryan's agent suggests that Ryan gain five pounds of muscle because it's equivalent to a "normal-sized" person adding 20-25lbs. Just as Ryan gains a pound and feels stronger, he suffers a bad fall during a race. The fall is a setback, but he's riding again and just started getting back into the gym. He is currently third in the standings for Maryland jockeys and is still hoping for a Preakness mount.
Kevin is 19 years old. In 2002 he was named the strongest teenager in the United States. Since then his goal has been to become a Professional Heavyweight Strongman. Most don't peak until their early 30's, when muscle becomes more developed--but Kevin has always been strong for his age. Kevin is 6'3 and weighs 245lbs. The majority of competitors he'll face weigh anywhere from 300-350lbs. To gain weight, he is supposed to consume an average of 7,000 calories a day. Despite eating non-stop over the course of two months, he fails to gain any weight, but he's gotten stronger. He attributes it to the intensity of his workouts. Kevin trains for the competition events performing things like a car-dead-lift hold, lifting Atlas stones, and pushing log over his head. He goes into the competition feeling pretty drained, worrying that he over-trained. Amazingly, he is in first place going into the final event in the competition, but ends up dropping an Atlas stone and loses by three seconds. Two months later, Kevin placed first and is now a professional Strongman.
