Amanda Turcotte wants to be all that she can be, but she's 25 pounds over
the Army's weight limit.

Her recruiter is sweating her down to regulation size with a grueling
daily exercise regimen.

"If you need to puke there's a garbage can right there," Army recruiter
Sgt. Jessica La Pointe told Turcotte during a recent workout at an
Annapolis high school. "That's fine. You can come back and finish up."

With fast-food diets and couch potato lifestyles expanding the waistlines
of the nation's youth, the former professional kickboxer says she must
become personal trainer to many recruits just to get them to boot camp.

"We do get people who come in the office that are overweight by Army
standards," La Pointe told ABC News. "And then what we do is try to work
out a program through nutrition and exercise."

The standards vary by service. The Army allows 26 percent body fat for
men, and more for women. When recruits are asked their weight, "everybody
lies," La Pointe said.

Obesity is a national epidemic. Three in four military-age Americans is
unqualified to join the military. The No. 1 reason: obesity. One in five
military-age Americans is too fat to serve. The military has turned away
48,000 overweight recruits since 2005, more than all the American troops
fighting in Afghanistan.

Leo Knight-Inglesby was one of them. Two years ago, when he wanted to join
the Air Force, he tipped the scales at 361 pounds -- way over the Air
Force limit.

"I was eating everything in the house," Knight-Inglesby told ABC News
during a break from basic training. He said a recruiter told him, "You
need to lose some weight -- a large amount of weight."

He's now at Boot Camp at Lackland Air Force Base in San Antonio, Texas,
after dropping a staggering 161 pounds. He said he did it the old-
fashioned way -- exercise, and dropping a daily McDonald's habit.

Tech. Sgt. Scot J. Morin, who oversees physical training at Lackland, has
seen the slide in fitness.

"Some of them come down here and they've been on the couch for the past 18
years and haven't run a lick," he told ABC. "When I first got down here
the trainees that were coming in were in a little more in shape than they
are now."

As the nation's armed forces are stretched by wars on two fronts, an
increasing number of recruits never make it past the recruiting office
before they're told they're unfit to serve. Curtis Gilroy, the Pentagon's
accessions chief, said obesity amounts to a national crisis, and it makes
a tough job filling the military's ranks even tougher.

"It's clearly a problem for the United States military," Gilroy told ABC
News. "We're faced with a dwindling pool of the youth population in the
17-to-24-year-old group about which we are very concerned," he said.

Turcotte hopes to be wearing Army green within the month.

Asked if two-hour-a-day workouts are worth it, she said, "Totally.
Definitely worth it. ... One more inch off my waist and two more inches
off my hips and then I'll be good to go."
