Dance to music, aerobics, yoga, martial arts, Tai Ji Chuan, lie on your back at both ends, lie on your stomach at both ends, run on your legs, stand upside down, ride a horse, lift your legs sideways (this requires equipment, hehe), support your head, back and legs in a straight line with your elbows on your stomach, and support your head, chest, abdomen and legs in a straight line with your elbows on your back. On this basis, the difficulty is increased. One elbow is supported, the other arm is stretched forward, and the opposite leg is bent at the same time. The elbow support can also be replaced by hand support. Worm crawling, which is more interesting, from hand to foot, from foot to hand, hehe. That's all. Play first.
