First: pull-ups
Everyone has done pull-ups, and here I mainly share with you some points that need attention. In the process of completing the movement, if you feel that your physical stability is weak, then you can choose to cross your feet during the exercise. Beginners can start with elastic belt's assistance or ask someone to help them practice. You can also do some transitional exercises, such as straight arm hanging, bent arm hanging, low bar oblique pull-ups, hanging pendulum, low bar supine pull-ups (one person lifts legs), various push-ups, bent arm pull-ups and other exercises.
Second: high level pull-down
High drop-down is an action for beginners. At the beginning, I mainly did pull-ups, but because of my weak sports ability, even one group was a little reluctant. Later, a friend recommended this action. After personal test, I really feel that although the effect is not obvious as pull-ups, it is still very effective to exercise back muscles. When a novice does this action, don't just use the gravity of the body to exert force, but take the stability of the body as the premise, otherwise it will easily damage the lumbar spine.
It can be seen that in fitness, especially back-related sports, mastering methods and correct posture is a shortcut, so add back exercises to your fitness plan.
