Burpees are one of my all time favorite exercises. Few movements hit as many muscle groups and deliver as intense a cardiovascular workout. After performing 10, no matter how fresh you are, you will be breathing heavily. After performing 75 consecutively, you’ll be on the floor for 5 minutes like a boxer down for the count.
Burpees basically combine a squat, pushup, and vertical leap. Think about the amount of mass (your entire body weight) you move over a large distance (your full height plus the height of your vertical leap) and you’ll understand just how many calories you can quickly burn with this exercise.
The Wikipedia article on burpees gives a good explanation of the basic movements.
