Flat dumbbell bench press exercises pectoralis major. This action is very important for the requirements of action standards. If you don't have a standard movement to bench press, we will find it easy to borrow your arm, which makes it difficult for us to keep our chest and get enough exercise. A key point of this action is to keep your arms open as far as possible when pressing the bench, keep the pectoralis major in the maximum stretching state when putting down the dumbbells, then draw an arc with your chest, and finally lift the two dumbbells to the position where they are combined on your head. If we lift the dumbbell straight up and down, we will find that the arm leverage is obvious, which has less influence on our pectoralis major, so if we want to make the pectoralis major exercise better, we must strive for the minimization of the arm leverage.
Secondly, if you do a heavy lift, someone must hold your wrist to help you, because if you do a flat dumbbell bench press, it is easy for us to lift the dumbbell straight up and down when we are exhausted, resulting in the effect of one of our exercises is not particularly obvious. If someone lifts up to help you hold your wrist, we can better regulate every movement and be more beneficial to our chest muscles.
