A strict exercise activity designed only for the most serious of athletes. This physical activity is where the subject gets on their hands and feet and arches their back as high as they can. Once their back is arched they move in a powerful thrusting motion forward with their head up. The subjects legs and arms resemble that of a bear crawling but are more extreme angles and are moving very fast.
