Nine million American students are packing on too many pounds,
But just as kids are being told to exercise more, they're finding fewer opportunities to break a sweat during the school day.
The physical education classes of then, are disappearing now.
Tiffany McGinley, Kindergarten/First Grade teacher, said: "They're developing the muscles of their body."
Tiffany McGinley said: "Unfortunately with budget cuts, hum, our PE instruction time has been cut."
Only six states require the recommended 150 minutes of elementary PE a week and just three states have 20 minutes of mandatory recess a day.
At this school for autistic children, there's one PE Teacher for all 160 students. This is helping the kids stay active.
"Adventure to Fitness" is a free interactive workout for kids. It exercises students' bodies and minds.
McGinley: "Kids! the Statue of Liberty is on Liberty Island."
Adventures that get the kids running, hopping, squatting, and leaping for 30 minutes straight. Marc Loyd leads adventures for 60-thousand teachers in 11-thousand schools.
Marc Loyd "a.k.a" Mr. Marc, adventure leader, said: "We're never telling our adventurers, that's what we call them, to do a jumping jack, but there is always a reason behind why you might do jumping jacks in one of the episodes; it's because you're cold and your down in a cavern so you need to do jumping jacks in order to get warm."
Luis Hernandez is the lone gym teacher for 800 kids. He says the program is making a difference.
Luis Hernandez, PE teacher, said: "The kids are more active, they're more, hum, willing to exercise and do things they wouldn't try before."
Valeria Hernandez, 1st grader, said: "It gives me good exercise."
And there's only one rule.
"We never stop moving!"
