Exercise is actually one of the best ways to treat depression, so some people like to go to the gym when they are in a bad mood. During exercise, the concentration of serotonin in the human body will increase, producing endorphins and norepinephrine, which will directly enhance positive emotions, relieve stress and depression, and increase happiness.
Most people are too eager to lose weight, too eager to get stronger, too eager to see the results, but often ignore the most important point: many "accomplished" trainers in the gym, if you carefully observe their training, most people's movements are not good, and these bad problems often appear in squats (movement track deviation), hard pull (waist pull) and pull-ups (including chest).
It is also common to see some people staggering or even squatting on the empty pole and getting heavier. There are also many people doing a lot of exercise and bad posture training ... it is undeniable that as long as you have training, you will have some good results. Helping to pack dumbbells in the gym every day is actually effective, but it is useless in the long run! And the wrong posture continues, and finally the whole body is injured, shoulder pain and low back pain come to you!
