#2: plank crunches
This exercise trains the muscles of the whole body and pumps the press well.
You need to lean on your forearms and feet in order to properly perform this exercise. But it is important to feel the main tension in the center of the body. It is enough for beginners to stay in a static plank for a minute, and people with stronger physical fitness can also twist the body, turning the chest to the right and left, using the oblique abdominal muscles. To make it easier to hold out for a minute, it is necessary to alternate tension and relaxation of different muscle groups.
On a note: Constant stress is the “enemy” of a flat sports belly. This is due to the increased production of cortisol – this hormone contributes to the accumulation of abdominal fat.
