First, lift weights with both hands, and open your hands parallel to your shoulders. The first action can be done standing or sitting. No matter what kind of posture, we should pay attention to finding the support of the abdomen to avoid the body doing movements in a loose situation. We should first choose a dumbbell with the right weight, then take protective measures on our hands before lifting the dumbbell, then slowly open our hands, lift the dumbbell by the strength of our arms to a height parallel to our shoulders, and then slowly drop our hands for a few seconds.
Second, lift weights with both hands, and raise your hands forward to be parallel to your shoulders. The second action can be standing or sitting, and you need to find the support of your abdomen. Ready, let's pick up the dumbbell with our hands, and then slowly raise our hands to our chest. At this time, our hands should be in a parallel state, and the height should be as high as the shoulders. These two movements can effectively exercise our shoulder muscles, and after a long time, they can also make our arm lines more beautiful, but only if the movements are standardized, otherwise the effect will not be much better.
Third, the last action of standing against the wall needs to be maintained for a long time, which is what we often call standing against the wall. When we stand against the wall, we also need to find the support of the abdomen, and then let the shoulders open a little, and the shoulders can be raised a little, as long as they don't droop, but don't lift the shoulders too high, let the shoulders be raised. This action only needs to be kept for ten minutes every day. Over time, you will develop the good habit of holding out your chest, and your shoulders will naturally not sag.
