Elbow forward slightly can strengthen the exercise of the front of deltoid muscle. In order to get more exercise in the middle of deltoid muscle, elbow abduction, fitness muscle and support can help practitioners to reduce their attention to body posture and concentrate on exercising deltoid muscle.

2, deltoid middle bundle

There are two ways to push dumbbells while sitting. One is that our fists and eyes are facing each other after lifting the dumbbell, and the other is that our palms are facing each other. Either way, you can stimulate the front and middle bundles of deltoid muscle. However, if you want to stimulate the toes of deltoid muscle more, you'd better choose the palm-to-palm method.

Extended data:

Sitting posture is safer than standing posture. When standing and pushing shoulders, the waist is under great stress, because the load of the upper body will increase the pressure on the waist. Especially when carried to the top of the movement, the lumbar spine is under greater pressure because of the elongation of the arm of force. Sitting posture pushing shoulders can increase the stability of the body, especially sitting posture pushing shoulders with backrest. We distribute a lot of force to the backrest stool. Thereby making the operation safer.

The sitting posture is more stable and the weight can stimulate the deltoid muscle more intensively. In other words, from the training effect of deltoid muscle, sitting shoulder push is better than standing shoulder push. ?

Standing shoulder pushing is less irritating to our target muscles (shoulder muscles) than sitting shoulder pushing. However, it is better than sitting posture to push shoulders in overall strength and muscle development.
