The bear crawl is walking on all fours with your belly facing the floor (the opposite of the crab crawl). This movement can be a good whole-body exercise that challenges kids to use their limbs and core.
First, simply have kids practice this movement, then work toward using the bear crawl in more complicated games, such as doing an obstacle course or challenging them to race to a certain location in the house and back.
With care, they can also leap over each other’s backs in this pose.
