The caterpillar exercise offers a little bit of everything - it helps to strengthen the muscles of the anterior chain (the front half of the body), while simultaneously stretching the muscles of the posterior chain (the back half of the body). And since it is more or less aimed at your whole body, this exercise makes your blood boil. Therefore, a reasonable solution would be to include the caterpillar in the warm-up plan of a high-intensity workout.

The movement itself eventually looks exactly the same as its name - caterpillar.
