Three major disadvantages of pull-ups

　　Pull-ups are a common fitness exercise, but if you don't pay attention to the method, it may also cause some harm. The following is a detailed introduction to the three possible harms of pull-ups.

Muscle and joint injury risk

　　Muscle strains and strains: When doing pull-ups, if you do not warm up enough or overtrain, it is easy to cause muscle strain. For example, if you suddenly increase the number or intensity of pull-ups, the muscles of your shoulders and back may not be able to bear it, resulting in strain. Long-term incorrect posture can also cause muscle strain. Postures such as rounded shoulders and hunched back will put greater pressure on the rotator cuff muscles and increase the risk of rotator cuff muscle injury.

　　Joint wear and inflammation: During pull-ups, repeated movements of shoulder joints, elbow joints and other parts will cause joint wear. Especially if the posture is wrong, the joints will bear uneven pressure and the wear will be more serious. Over time, it may cause synovial inflammation, tendonitis, etc. disease , such as lateral epicondylitis, also known as tennis elbow, can cause pain and inconvenience to patients.

Hormones and body dysfunction

　　Hormone imbalance: Excessive high-intensity training such as pull-ups can cause hormone disorders in the body. Cortisol rises and testosterone levels fall. Elevated cortisol breaks down muscle protein, affecting muscle growth and recovery ； Decreased testosterone levels will reduce the body's metabolic rate and strength levels, and may also affect sexual function and mood.

　　Immunosuppression: Long-term overtraining can put the body into a state of stress, leading to immune suppression. Decreased immune system function makes the body more susceptible to pathogens such as bacteria and viruses, increasing the chance of illness. For example, after overtraining, people may be more likely to cold , Infection with other diseases.

Psychological and movement deformation issues

　　psychological boredom: When pull-ups enter the training plateau and it is difficult to make progress, many people will feel psychologically bored. This emotion can affect training enthusiasm and motivation, and may even lead to giving up training. Moreover, a poor mental state will further affect physical performance, forming a vicious cycle.

　　motion deformation: In order to complete more pull-ups, or when they are physically exhausted, people tend to deform their movements. Movement distortion will not only reduce training effectiveness, but also increase the risk of injury. For example, incorrect postures such as hyperextending the spine and tilting the pelvis forward during pull-ups will put excessive pressure on the lumbar spine and increase the possibility of intervertebral disc damage.

　　Pull-ups are a favorite fitness exercise for many people, but they need to be scientific and reasonable when performed. Excessive pursuit of quantity or incorrect posture may cause various healthy question. Understanding these potential hazards can help us better protect ourselves during exercise.
