Squat is a kind of physical exercise, mainly relying on the strength of legs and waist. Legs in the same plane, body upright, moving up and down. Generally, when squatting, you should control the frequency and timing of breathing. It is suggested to inhale when squatting and exhale when squatting, which can better practice squatting and achieve better results.

Squat is a good exercise, which is beneficial to the human body, but it is not recommended to exercise for too long, because it is very harmful to muscles, and it is prone to discomfort such as muscle soreness and fatigue, which affects health. Generally, it is suggested that the squatting time should be controlled at about 30 minutes and divided into 5-8 groups, with a rest between each group 1 minute.

Squat is the trump card for practicing thighs. Squat is an action that requires great lung capacity and a strong heart. The standard of squat is to keep the back straight and the hip joint lower than the knee joint. Incorrect technical movements can damage the knee joint. Squat for 30 minutes. If it is negative weight exercise, it can be regarded as aerobic exercise. If it is a negative moderate or even heavy exercise (there should be a rest in the middle), this is anaerobic exercise.

People who insist on "Inhale when squatting and breathe when getting up" believe that the pressure in the chest and abdomen will also act on the cardiovascular system of the trunk, and this increase in pressure will be transmitted to the head through blood vessels, which may lead to accidental cerebrovascular injury. However, this kind of worry seems unnecessary, and they ignore several facts. Most importantly, if the pressure across a diaphragm will damage the diaphragm, there must be a pressure difference, that is, the pressure on both sides of the diaphragm must be different, otherwise the diaphragm will not break. When we do squats, when we use flat breathing, the overall pressure increases, and there is no pressure difference at any boundary.
