Definition of burpee

*plural burpees
:a conditioning exercise in which a person squats, places the palms of the hands on the floor in front of the feet, jumps back into a push-up position, in some cases completes one push-up, returns to the squat position, and then jumps up into the air while extending the arms overhead

The workouts mix up drills of common exercises like burpees, squats, jumping jacks, lunges and variations of push-ups. —Pablo Alcalá, Lexington (Kentucky) Herald Leader, 17 Jan. 2013**
