The full-body exercise where you drop into a squat, kick your feet back, then return to standing is a burpee.
The modern burpee is based on the “burpee test,” developed by American psychologist Royal H. Burpee in the 1930s as a quick measure of physical fitness. His original version was simpler and did not necessarily include the push-up or jump often added today.
A standard burpee usually involves squatting, placing the hands on the floor, extending the legs into a plank, bringing the feet back underneath the body, and standing or jumping. Because it combines lower-body movement, core stabilization, and rapid changes in position, it can raise the heart rate quickly.
A common mix-up is the squat thrust. A squat thrust has a similar leg-kicking motion but traditionally ends without the extra stand or jump. Variations such as push-up burpees, no-jump burpees, and broad-jump burpees change the difficulty while keeping the basic movement recognizable.
