Pull-ups can't be pulled up mainly because of lack of back strength, overweight and lack of rest. The solution is mainly from four aspects: strengthening back strength, reducing weight, arranging rest time and carrying out auxiliary training.

Lack of back strength

Pull-ups depend largely on our arm and back strength, especially forehand pull-ups, which require higher back strength. However, our backs are often lack of exercise in daily life and fitness, and it is normal that they are not able to pull up.

be overweight

Pull-ups are a kind of resistance training, and the resistance against them is our own weight. If the weight is too heavy and the gravity is too great, then the strength of the arms and back can't be pulled up.

Not enough rest after training.

After stretching and contracting exercise, muscle fibers will be slightly torn and broken, and muscles at this time need to rest for a certain period of time to resume growth. If you don't have enough rest time, then your muscles are in a state of fatigue and naturally unable to pull up your body.
