Exercising with young children

Consider using family time to get more physical activity. What kid doesn't like to play catch? A ball or frezzbie is great for this.

While out for a walk or jog, have your kids ride their bikes alongside you, just make sure it's not an unsafe street.
While walking around a school track, your kids can play on the infield. Being with your children can go hand-in-hand with keeping fit. An added benefit is that they see that you value physical activity.
