Dumbbell bench press requires adduction of the shoulder and spleen bones to ensure the stability of the shoulder and spleen bones, without shrugging or sinking shoulders. There is no need for a bridge at the waist, but at least one fist can be put in.

When reaching the lowest point, the angle between the elbow and the arm is 90 degrees, so it doesn't need to be too low, because too low will lead to excessive stress on the toe of the deltoid muscle.

Different from barbell bench press, dumbbell bench press will require many people to shake hands at first, and three heads are more likely to be exhausted. There are not many good methods at this time. You need more training to strengthen your arm strength.

One way to improve hand trembling and three-headed fatigue is to change the "push" mode to the "clip" mode. Push in chest training is essentially a clip rather than a push. As long as you master this trick, you will get twice the result with half the effort.
