My son is a wizard when it comes to digital devices. Hand him an iPhone, iPad, or iMac and he’s right at home. But as much as I appreciate his tech skills, I’m not a big fan of excessive screen time—or the posture-destroying, sedentary behavior that comes with it.

To counteract the effects of extended device use, I implemented a simple rule: for every 30 minutes of screen time, he must do 10 squats, 10 push-ups, and 10 leg raises.

That’s 30 reps every 30 minutes—and guess what? He’s been doing it! He walks over to the kitchen timer, sets it for 30 minutes, and once it beeps, he gets to work.

It’s an easy, effective way to build activity into a child’s routine, especially if they’re spending more time indoors. If they’re not out playing street hockey like we used to, at least they can move a little inside the house.

Try it with your own kids—make movement part of their digital routine!
