Aren't some boys especially fond of practicing their arms? The more obvious the muscles on the arm, the more masculine the feeling, the more effective the fitness, and the more attractive the attention of girls.
Don't use oversized and overweight dumbbells when practicing biceps brachii. Even if you can carry them, they will be strong. It will put a lot of pressure on your tendons, thus losing the effect of exercise.
However, if you want to exercise your physical fitness seriously and make your whole body look good, I suggest you focus on exercising your core muscles.
Core clusters can make your body more harmonious, but when you exercise, all the muscles of your body become strong together, unlike some people who have fat on their stomachs but strong arms.
It is generally recommended to train the core muscles and the back muscles at the same time, so that your body will not be uncoordinated, for example, because the pectoral muscles are too big, there will be a hunchback.
The training of core muscles is generally belly rolling, flat support, leg lifting, and equipment can also be used. However, after the belly roll, the research shows that there is great pressure on the muscles and spine of the waist, and it is recommended to use flat support.
If you hang your legs, many people may not be able to do it, such as me, because some people have a poor sense of balance. Of course, you can also make a hip bridge on the yoga mat. The gluteal bridge can not only exercise your core muscles, but also your back muscles and your gluteal muscles. So those who like peach hips can 100 hip bridge every day and try the final result.
