Keeping kids active is a real challenge. I agree with Michelle in that we don't let our kids roam free outside any more - but with the heightened awareness of our kids' safety and security, it is no wonder. I recently signed my 14-year old up for a program www.getsweaty.com to encourage him to get some movement each day. Being a computer-based program, he's likely to give it a go. We also require time of intentional physical activity before he is allowed to play video games or watch TV (1/2 hour of excersize gets him 1 hour of 'screen time'). Initially he decided that he was outsmarting us by just reading a lot, but after a few days decided it was worth the effort.
