Don’t only train the chest muscles without training the back muscles
If you spend a lot of time training the chest muscles without taking into account the upper back muscles, this will cause an imbalance of muscles and joints, and ultimately lead to poor posture. Increased risk of injury.
Rational training is to strengthen the exercise of the upper back muscles. Do as many sets of chest muscle exercises as you do the upper back muscles.
If an imbalance is now created, then you should invest more time in strengthening your upper back muscles.
