The bear crawl sled drag is an advanced variation of the bear crawl exercise involving added resistance from a sled or other weight. If no sled is available, other viable options include dragging chain, a barbell plate, or a tire. The bear crawl sled drag is an intense full-body movement that targets the cardiovascular system as well as a wide range of muscle groups, particularly the shoulders, core, and legs. It can be done in short bursts for power or circuit training, or for longer durations as cardiovascular conditioning.
