One: Push-ups mainly exercise the muscles of upper limbs, waist and abdomen, especially the chest muscles. It is a very simple but effective strength training method. Beginners can practice push-ups in two groups, 5 to 10 times in each group.
Two: sit-ups, a form of exercise. Lie on your back, put your legs together, raise your hand, contract your abdominal muscles, swing your arms forward, and quickly become a sitting position. Keep your upper body bent forward, touch your feet with your hands and bow your head. Then return to the sitting position.

After long-term exercise, its main function is to stretch the whole spine of human body, including cervical vertebra, thoracic vertebra, lumbar vertebra, cervical vertebra and coccygeal vertebra, which is beneficial to exercise and ensure the correct physiological curve of human spine, which is rare in other sports.
