There are not many movements in trapezius exercise, basically barbells and dumbbell shrugs. Barbell shrugs can be done in front of and behind the body. Personally, I am also pursuing trapezius girth.

Deltoid muscle moves more.

First of all, deltoid muscle is divided into anterior bundle, middle bundle and posterior bundle.

The toe, dumbbell and barbell are pressed on the head, and the effect is very good. At the same time, they can also be exercised when doing chest movements

Middle beam, front horizontal lift and side horizontal lift (only standing birds) can be effectively exercised. Don't use too much weight when doing these two movements, or you will ask trapezius muscle to support it. Don't think it's good, so you can't exercise deltoid muscle well, nor can you practice trapezius muscle well. Another movement is rowing upright with barbells.

Back beam, bend over the bird, and also use this muscle in the bending action of the back.
