Exercise is an important part of a healthy lifestyle. So why not get your kids into a good exercise routine when they're young? You can certainly do that by designing a home gym with their needs in mind. Paint the walls with bright primary colors and hang images of their favorite cartoon characters -- think SpongeBob SquarePants lifting weights. Add fun equipment like an indoor jungle gym and a flat-screen TV with gaming system where they can play workout video games. You could also paint a hop-scotch pattern or other "sidewalk chalk" creations on the floor, and incorporate other outdoor activities like jump rope or a stationary bike to get their cardio pumping. With a fun design theme and the option to workout together as a family, you may even see better workout results.
