1, low posture crawling is a kind of exercise mode with the body flat on the ground and reduced to the lowest degree, which is generally used when the height of the bunker in front is about 40 cm.
2. The lateral position is an exercise mode when the front bunker is about 60 cm high, which is characterized by a slightly faster movement speed but a higher posture.
