1, as long as you master the scientific method, use it a little, and stick to it, a pull-up action can help you fix your upper body muscles.
Unfortunately, it is very difficult, very difficult. If you just start practicing, you may not be able to complete a movement. This is a daily - happened thing. The more difficult it is, the more you can widen the gap with others. When you can independently complete the standard movements of 15 times, you will find that you have fallen behind others in upper limb movement.
2. Pull-ups are compound training movements. Sticking to this action for a long time can improve the strength level in an all-round way, constantly improve your muscle strength and muscle volume, and thus improve your strength and body. Pull-ups are simple. Hold the horizontal bar with both hands wide, keep your arms straight, droop, relax below the waist and back, and straighten or cross your calves. Inhale and pull up, exhale and restore.
3. From the grip direction, pull-ups can be divided into two methods: front grip and reverse grip.
It can be simply understood that the grip method of holding the rod forward with the palm of your hand is called the front grip method; Holding the palm backwards is called reverse holding; Generally, the grip distance of the palm backward is shoulder width, and the muscles involved in this movement are latissimus dorsi, deltoid posterior bundle, biceps brachii and forearm muscles; The palm forward movement is generally wider than the shoulder, and the muscles used in this movement are latissimus dorsi, biceps brachii and forearm muscles;
4. Forehand pull-ups, palms forward, less stress on biceps brachii, greater stress on back and greater difficulty; Backhand pull-ups, palms facing yourself, biceps exert more force and are less difficult. Therefore, backhand is usually done more times than forehand;
