My Take
The academic brain breaks are a little generic, but many can be customized if you take the time. My students love to watch the class monster grow and change. There are a variety of activities to choose from at varying activity levels. I know from experience that an exceptionally wiggly class is more ready to learn after a high energy Zumba song.
How I Use It
I've used brain breaks in my classroom for several years, but GoNoodle makes them easier and more fun. I teach in STEAM Lab and only have two minutes between classes. I can put on a brain break from GoNoodle and be confident that my students will be engaged while I finish setting up for the activity. It is one of the websites I keep open in a tab all day. Anytime we need to get our wiggles out or have just a few minutes between activities, we use a brain break from GoNoodle.
