Functions are relative. The earliest functional training is self-physiotherapist training for the purpose of rehabilitation, which aims to restore generalized function to patients who lack complete functional ability. At present, the functional training for the general public or athletes is more functional in a relatively narrow sense, that is, the functionality to improve the quality of specific movements. For example, the functional training of lower limbs (including one-leg hard pull, one-leg squat, lunge jump, etc. ) can help weightlifters improve their snatch ability or sprinters improve their sprint ability. In the process of daily strength training and fitness, properly adding the assistance of functional training can improve strength, improve the level of the three major items, reduce injuries and improve posture.

Functional training of the body emphasizes the movement of multiple joints and dimensions, plus the participation of problem receptors to regulate load and strength. The key point is to cultivate people's sports mode and improve their competitive ability and flexibility. Stability is the mode efficiency of human body.

Functional training is inseparable from core training.

The so-called core strength is an important part of "functional training" and a subsystem of functional training. Core strength is a kind of strength ability, which can effectively stabilize the core area of human body, control the center reasonably and effectively, and transmit energy. It is an important "power source" for human body. Improving the core strength can not only improve the competitive ability of trainers, but also effectively prevent sports injuries of trainers and reduce the injury rate.

Functional training is also of great help to people who practice muscles. Trainers may use a lot of weight to stimulate muscles when practicing muscles. When the core is unstable, the body will shake, which greatly reduces the quality and effect of exercise, and may be injured in serious cases.

Functional training is a diversified training, which can meet people's various purposes, or exercise around muscles. All sports are inseparable from unhappy lung function. Muscle exercise has no good cardiopulmonary function, and it is also futile to exercise muscles, because we will produce some waste through resistance training, which is what we often call lactic acid, but this lactic acid is washed away through our blood. If we take enough oxygen in resistance training, our exercise effect will be greatly improved.

"Tall buildings rise from the ground", so the foundation of exercise is very important. So people who are new to fitness can start with the most basic training. First, they can train with their bare hands and slowly use some small devices in functional training. After all, training is not a short-term thing, but a long-term process, so laying a good foundation for sports will make you go further and further.

"Fat reduction" is a very popular course in the gym at present, but do you know that core strength is also important for fat reduction? Whether it is action or explosive force, agility, stability, etc., it needs a strong core to support it. If our core is unstable, losing fat is easy to deform. It is difficult to find the center of gravity of the body, and all muscles participate in exercise, which will be very unfavorable to the exercise effect.
