Most parents admit that winter isn't the easiest time to get kids exercising outdoors when the couch is so warm and inviting. So, if you're looking for ways to get your kids up and at 'em, why not encourage them to warm up with some heart-pumping indoor fun instead? Working up a sweat is easy when kids can stay inside and use purchased equipment or things that can be found around the house. Keep their enthusiasm up by encouraging them to participate in fitness activities they enjoy, and by being active along with them. Turn on a kid-friendly fitness video or a CD of their favourite tunes. They can teach you some new moves and you can show them some classics. Instill a love for physical activity and it will stick with your kids through rain, sun and snow.
