1, tightening the core, usually we say tightening refers to the important muscle groups around the body in the front and back of the abdomen, which is responsible for protecting the stability of the whole spine. Sucking the stomach is just an ordinary action.
2. When sucking the stomach, our chest will swell, our ribs will evert, and our abdominal muscles will not exert force and will not play a protective role; When the core is tightened, our ribs will come down and our abdominal muscles will become hard when exerting force. At this time, the core can be stably protected.
There are three reasons to tighten the kernel:
1. flatten the abdomen. Tightening the core muscles does not mean contracting the abdomen. In fact, this action is more like tightening your abdominal muscles and forming a protective ring around your torso (like an invisible belt). When you laugh, sneeze or cough, these muscles naturally contract. Regular exercise of these muscles will reduce your waistline by a few centimeters in appearance and feeling!
2. improve posture. Don't just sit up straight, but tighten the core to achieve the best posture. When the abdomen is relaxed and the lower back is tight, a great curve will accumulate on the spine, which will affect the position of pelvis and the state of the whole body. It is very important to maintain good posture, which can keep your joints, bones and muscles and reduce the risk of injury.
3. Relieve back pain. Eliminate the tension in your back, neck and shoulders, and make you work more comfortably. When the abdomen is tightened, the spine will straighten. When the abdomen relaxes and protrudes forward, the lower part of the spine bends inward, which is the most common cause of low back pain. Therefore, correcting abdominal relaxation and lordosis is the first priority.
