Finding simple and fun ways to stay active is our final Fit Kids February Challenge. NY1's Erin Billups filed this report.

Experts say kids need an hour of physical activity daily to stay healthy and reduce the risk of chronic diseases later in life.

"Children won't be regimented and look at a 60 minutes period of time and say this is their exercise time. So the Heart Association advocates not just 60 minutes, but breaking it down into two 30 minute blocks," says Dr. Lawrence Phillips of the American Heart Association.

Finding the time to fit in that moderate to high physical activity may seem difficult, but physical therapist Paul Hartmann says it's easier than you think.

"To get active, you got to find ways to make it a game," says Mount Sinai Beth Israel Center for Health and Healing Physical Therapist and Rehabilitation Coordinator Paul Hartmann.

With the help of 12-year-old Amanda Lee, Hartmann showed us some moves.

"So standing on one leg, seeing how long they can stand on one and then moving the other leg. And then you repeat that without touching down. You see how many times you can do that sequence. And you make it a competition—who can do it more?"

Engaging core muscles—abdominals—are important. The plank works great for kids, too.

"You get down, you can start on your hands and knees and come down to your elbows and then you make a straight line with your body from your head to your toe. And then the goal here is to hold it for time so this is something that families can do for time," Hartmann says.

He says like adults, kids should be able to hold the plank for at least two minutes.

When taught the right technique, squats are also a good exercise to master young.

"That chair will be the goal to help her keep really good form. And then from there you can do reps," Hartmann says.

When your child notices her heart beating faster, and his breathing is heavier—that's the key.

Creating habits that will last a lifetime is the goal. Getting there will be easier as a family.

"They're watching everything that we do so if we spend all of our time watching television, then that's what they're going to emulate. But if we're out and we're exercising and we're kicking a ball with them then that's, those are the activities that we're going to reinforce in them," says Hartmann says.
