Brainstorm of Product

How does exercising/stretching help students in Kindergarten to Second grade stay focused on a task?

Progress check:
So far I have learned that doing stretches that cross your midline will also help the development of your right-brain, left-brain.  I also learned that students need about twenty minutes worth of exercising, and even though you won't be able to do that much in your classroom it would still be helpful to take short breaks to do a few exercises just to help your students stay focused on their school work.  I think the main thing I really need to focus on is getting my stretching/exercises to use in my final product. 

Target audience and Product:
My final project will mainly be projected to teachers, but I think parents could find use in it as well.  Teachers could use these activities for short stretching break(s) when she (the teacher) sees her students start fading out during the day and especially after lunch.  I think parents can use this idea of midline stretching to help their child with right-brain, left-brain activities at an early age. 
For my product I am thinking about videoing myself doing certain midline stretches and explain how to do it (kind of like in magazines but in a video).  If I don't do the video I will do pictures of me doing the stretches and explain how to do them.  With the video or pictures I would create a website to post them on so teachers and parents can go look at them or even play them in front of the classroom/children so they can follow along with me.
