boys' waists seem simple, but there are many small details worth studying.
The thickness of waist and abdomen: A study found that excessive abdominal fat obesity has a significant relationship with low brain cognitive level. The low level of brain cognition means that the memory is definitely not very good.
The muscles in the waist and abdomen: Everyone has abdominal muscles, and the key to our attention is the following two muscles. Latissimus dorsi , belongs to the superficial large muscle group of the waist, has strong explosive power and is suitable for exerting force. The external oblique muscles are in the lateral abdominal muscle area, and the lines are not obvious. It takes time and skills to practice them. These two boys with stronger muscles will have stronger physical strength and usually have good exercise habits, so they pay more attention to their image management.
The bones of the waist: A waist with excellent strength must have a healthy spine. The health of spinal bones is very important for daily life. From walking to moving bricks, you must have a healthy bone to support it. Due to long-term sitting and no exercise, many people have spinal problems, so everyone must pay attention.
