Newton's First law
"Any body will remain at rest or in its state of constant motion unless acted on by an outside force".
So turn off the TV and get those kids moving!!!
Here are some ideas:
1. Speed walk with them...is good for them, for your back and for your neck.
2. Jump rope..and see how many jumps per minute they can do and then have them compete against themselves.
3. Invest in a Wii video game... boxing or tennis will get you both moving!!!.
