In terms of training methods, the training methods of horizontal bar can be divided into two aspects, one is the 0-break 1, and the other is the pull-ups to improve the number of times. The muscles needed for pull-ups are biceps, triceps, deltoid, back muscles and forearm muscles. The best way to increase the number of times is to work hard and take three meals. But at that time, it was really impossible for people who couldn't pull up. So I mainly look for the training method under the horizontal bar 0~ 1, and cooperate with the skill of pulling the bar. I believe that no matter how weak and fat my friends are, they will definitely break through their sub-zero spell. The training actions of biceps brachii, triceps brachii, deltoid muscle and dorsal muscle include standing and bending the arm (the second arm), holding the chest high bar wide, standing over the head (or supine posture), holding the chest high bar narrow, butterfly chest expanding or supine pressing (deltoid muscle), holding the neck high bar wide and squatting back (dorsal muscle).
