A good segueway from the last post; what could compete with TV and video games? Ninja Training! Actually, Parkour is an even better option - all the acrobatics without the fighting. I can't think of a better way to introduce fundamental movement skills to kids. It started as an underground urban pursuit, but kids and adults can now take classes, at least in the UK. A few videos for your viewing pleasure:
A 4 minute segment of a documentary.
Teaching kids the basics on an obstacle course.
Seeing the world as an obstacle course (don't try this at home).
You can find a longer ~9min video on a parkour academy here. If kids/youth coaches are looking for new ideas to work on strength, balance, co-ordination and agility, I'm sure you'll find a few things you can use.
