LZ's statement is actually not comprehensive. It's not that the kind of training in the gym is just to gain weight. Regardless of the action, the key is to look at the training method. Generally speaking, choose a weight of 8RM, and each group will complete 1-8 times. This kind of training mainly focuses on developing muscle strength, and the increase of muscle dimension is not obvious. The second is to complete 8- 12 times of training with the weight of 12RM. This kind of training focuses on increasing muscle dimension, followed by strength. Third, the training with the weight greater than 12RM (i.e. small and medium weight), and each group completed more than 12 times of training. This kind of training mainly focuses on sculpting muscle lines.

Push-ups need more auxiliary muscle groups to participate in the training of chest pushing with equipment. For example, push-ups not only need rotator cuff muscles and triceps like barbell chest push, but also need the participation of waist and abdomen muscles and leg muscles to stabilize the body. So push-ups are not as good as barbells in training chest muscles. Because too many muscle groups in your body will make your physical fitness decline rapidly, which will affect the training effect of chest muscles. However, it doesn't mean that push-ups are not good. If it is full-body training, push-ups are better than barbells to push the chest. Push-ups can not only practice chest, but also strengthen the core muscle strength of waist and abdomen. Adding push-ups to the training will make the whole training more diversified. So I didn't say which action was good and which action was not good. The key depends on your own training purpose and training plan. As long as you use the right action and the right time, then this action must be good. 、

Push-ups can fully exercise the chest, because the upward oblique bench press will be more focused on the upper bundle of pectoralis major, which is more targeted. In addition, downward oblique bench press can also effectively change the lower edge of pectoralis major, making pectoralis major more full and stylish. These push-ups are impossible. But push-ups and flat bench presses have basically the same training effect on the chest, except that one load is barbell and the other is one's own weight.
