As the saying goes, know yourself and know yourself. If you want to keep fit, you must first understand fitness. Here I briefly introduce the basic knowledge of fitness. Fitness literally means strengthening the body, but this body not only refers to the body, but also includes physical quality, which is generally divided into speed, strength, agility and flexibility.

So it is important to say that you can't just do strength training three times. Looking at those strong men who knock barbells and dumbbells every day in the gym, it seems that the equipment has a grudge against him. However, fitness really shouldn't just practice strength. You can focus most of your energy on strength, but other physical qualities can never be ignored.

Good flexibility and agility can help you complete the action better and improve the safety of the action. As for speed and endurance, it goes without saying that they can complement each other, so that your exercise can achieve better results and help reduce physical injuries. It's not just the gym that has all kinds of equipment or unarmed training.

I believe everyone knows this concept, but the specific classification of fitness is not necessarily clear. There are many standards for the classification of fitness types, which can be divided into aerobic and anaerobic exercises. Aerobic exercise refers to the exercise with aerobic oxidation as the main form of energy supply. To put it simply, it is generally less intense and lasts for a long time, such as jogging, yoga, dancing, spinning and so on. Aerobic exercise helps to improve heart and lung function, promote cardiovascular health and burn fat, which can help you maintain.

Fitness can also be divided into these two categories, one is instrumental exercise and the other is unarmed exercise. Instrument exercise is to use some instruments, such as barbells and dumbbells. Instrument exercise is necessary for strength training, and it is also the most obvious exercise effect. By increasing the weight, the heavy load borne by the muscles is increased, so as to produce the greatest stimulation to the muscles.

There are many kinds of unarmed sports, such as push-ups, pull-ups, long-distance running and other strength training.

There are various stretching exercises and yoga for flexibility training, as well as various aerobics and dance exercises for physical coordination and agility. Maximize stimulation, promote muscle growth and increase strength.

It is more important to understand why we do this, and what is the significance and theory of doing this. Only when we really understand this, can our fitness be more effective than others, and at the same time, we can increase our theoretical knowledge.

Simple mind is the misunderstanding of fitness. On the contrary, the more you know how to exercise, the smarter you are.
