We are seeing it in offices across the nation: workers using standing desks, ball chairs, under-desk ellipticals, all in a move to move more.
It has created a huge industry for active office furniture. Now that same movement is moving into schools.
Reporter Diana Olick shows us how schools are getting active in the classroom.
School is almost out, but the verdict is already in: kids who move more, learn better.
"I like all of the equipment," says Ilana Price, second grader.
Kid-sized pedal desks, standing stations and tiny ball chairs - all part of a pilot program at Oakridge Elementary School in Virginia, designed to get kids moving while they work.
And it worked.
"What's fun about a bouncy ball chair? You can bounce on it," says Amir Rustamov, second grader.
"Some of the behaviors that teachers noticed increase were time on task, cooperation with each other, having an opportunity to sit and read for longer periods of time," says Principal Lynne Wright, Oakridge Elementary.
The idea came from mom Heather Sauve, who wanted to keep her energetic son on task.
"Even if I do before school fitness programs and recess and lunch and P.E. class, there's just an abundance of energy," says Sauve.
So when she saw a picture of a pedal desk online, she was sold.
Sauve chose equipment from Kidsfit. The company, founded in 1997, initially made kid-sized fitness equipment for gyms and therapists.
Four years ago, they started seeing demand from schools.
"We wanted to make a difference in kids' lives," says Ed Pinney, Kidsfit owner.
So Kidsfit started making active classroom furniture, and never looked back.
"We built all the equipment and everything we did was based on that science that says there is a direct correlation between a healthy child and a smart child," says Pinney.
"It's a mindset, the children move. We went from having them walk in silent straight lines in the hallways to letting them have quieter conversations and wiggle as they walk down the hallways," says Wright.
They also went through rigorous teacher and kid training, and there have been no injuries, only pleas for more.
"It's going to be quite a feat, but we're willing and we're going to try and give it our best," says Sauve.
In other words, she'll keep the balls rolling.
