Put a hand trigger on each hand then go on your hands and knees. Crawl with alternate hands hitting the floor in time to the beat. NB the opposite leg should move in time to the hand.
Crawl backwards when you reach the end of the room, continuing in time. If you have headphones with a cord only crawl within the confines of the cord length backward and forwards or do not use headphones and put the laptop on the floor at the end of the room so you can see the visual guides as you crawl back and forth.
