Classfit Kids was one of my favorites. Jay & Pete Driscoll are the creators of Classfit kids and presented to a large group of PE teachers. The program is a 4 minute workout utilizing a form of interval training called Tabata. Set to music, this program provides students the opportunity to perform movements for a time period of 20 vigorous seconds, followed by 10 seconds of rest for eight intervals.
I'm excited to bring this program back to our school and share it with others. It would be a perfect way for classroom teachers to take a movement break with their students right their in the classroom. These movement breaks can reenergize students and make them better prepared to learn.
