The chest muscles exercised with dumbbells are beautiful, with clear contours and lines. The chest muscles from push-ups are strong, but they lack outline, that is, there are no lines where the chest muscles connect with the abdomen.
The dumbbell exercises the pectoral muscles and trapezius muscles: Lie flat on the bench and do three groups of spreading wings (arms and body are T-shaped when viewed from the front). Lie flat on the bench and spread your wings in three groups. 1 group can't move until you can do it. The number of people in the second group is appropriately reduced, and the third group is reduced by several more than the second group.
Let me tell you the effects and consequences since I did push-ups. Doing push-ups for a long time can exercise strong chest muscles, trapezius muscles and triceps brachii, and also improve abdominal muscles to some extent. The disadvantage is that doing push-ups alone will lead to S-shaped side body, prominent shoulder blades on the back and sunken vest, which has no exercise effect on forearm and wrist. I hope my answer can help you!
