Here's a great way to have your kids move around and get some of their gross motor work done at the same time! Here are some additional ideas for kids to do:
-Spin three times
-Jump on one foot 4 times
-punch the air three times
-Touch your toes 5 times
- Crawl like a bear to the wall and back
-give yourself three big hugs
-walk like a crab for 4 steps

Turn off the lights and turn on your flashlight. Have your child try and place their finger on where the light is flashing. this is fun and inexpensive way to entertain your child while having them move around. You can make it more fun by having them place an "easy to take off sticker" wherever the light hits. 

Yoga can be challenging for some kids. Doing hand-over-hand or adding a funny story to the mix can make it all the easier. For example: "Downward dog" is suddenly "walking like a bear". 
The more fun it is for kids, the more likely they are to stay engaged and follow along.
