(CNN)Juliet Starrett and her husband were running the sack race at their children’s school field day when they noticed something was wrong — the kids couldn’t get into the sacks.
“A lot of kids at our school literally lacked the hip range motion to get into the sack and then were having difficulty jumping,” said Starrett, who lives in San Rafael, California and has two daughters, ages 7 and 10.
The couple’s company educates corporations, athletes and professional teams on movement, mobility, mechanics and injury prevention, and that day at the sack race “really freaked us out because we realized the only thing that could cause that kind of dysfunction in kids was sitting too much.”
They’d been recommending people minimize sitting and use standing desks for about seven years. The desks are no longer an anomaly in workplaces, especially after studies showed prolonged periods of sitting can be horrible for our health. But the sack race was the first time they’d considered using the desks in schools.
