First of all, learn "abdominal breathing": when inhaling, the abdomen expands; When exhaling, the abdomen contracts. This is a necessary training for people who practice yoga or make sounds. Helps to stimulate gastrointestinal peristalsis, promote the discharge of waste in the body, smooth airflow and increase vital capacity. When walking and standing, you should contract your abdomen and cooperate with abdominal breathing to make your abdominal muscles firm. I won't get used to it for the first day or two, but as long as I always remind myself that "I can lose weight by shrinking my abdomen", after a few weeks, not only my abdomen will be flattened, but my walking posture will be more charming.

Sit-ups are an anaerobic exercise. First, bend your knees and lie flat on the mat, and put your hands behind your ears (never behind your neck) or cross your chest. Exhale when the body rises, tighten the abdominal muscles and pause for a moment, then slowly lower the body and inhale. You can start the next cycle without touching the ground or forming an angle less than 45 degrees with the ground. It should be noted that you don't have to do it too fast every time, otherwise your abdominal muscles can't be fully exercised. In addition, when doing sit-ups, don't sit up completely, as long as the head, shoulders and upper part of the back are upward. If the upper body is completely seated, it is not the abdominal muscles but other muscles. When doing sit-ups, you should focus on your abdomen. Don't do it with your legs straight, it will make your waist uncomfortable. For the number of sit-ups, as long as it is moderate.

Leg lifts are better than sit-ups. Nothing happened. Pay attention to slow down when lifting and slow down when lowering your legs. Very tired.

Fold to do housework

Maybe you are a little lazy. Be a hard-working Cinderella from today. Remember an important rule: avoid light and focus. For example, don't use a vacuum cleaner when sweeping the floor, and consciously increase the amount of exercise with a rag and broom; Choosing to wash clothes and iron clothes at noon with high temperature will cause a lot of sweat; When you are hungry, make yourself a delicate slimming lunch. "Chefs" generally don't want to eat by themselves, just control your appetite and stand for half an hour after eating.
