With music pumping in the background, the kids in Terry Wade's physical education class are in constant motion, going from sit-ups to jumping jacks to curls with light weights.
After their 45-minute session, the sixth-graders who are sweating the most, or as Wade calls it, "burning butter," get stickers.
"My main goal and emphasis is getting these kids up and moving," said Wade, who teaches at Northrich Elementary in the Richardson school district in suburban Dallas. "It's 'Can this kid do this for a lifetime?' I don't care how good they are. I care if they're having fun."
Instead of team sports, Wade and other physical education teachers across the country are focusing more on individual activities that students can incorporate into their lives long after their school days are over.
Experts say the shift also helps gym teachers include children who are struggling with their weight. With individual activities, overweight students can work at their own pace, and not be left on the sidelines. And they can take part in lower impact activities like weightlifting, yoga or martial arts.
