Bodybuilding, obviously different from our daily "fitness", is a competitive event, with shaping the body as the core and developing the maximum muscle latitude as the goal, requiring adequate muscle circumference and low body fat.
In the off-season, bodybuilders usually increase the intake of calories and carbohydrates, maintain the intake of high protein, and carry out heavy weight training in order to increase the circumference as much as possible.
Practically, bodybuilding can't be compared with CROSSFIT, but this comparison is worthless. Even the top volleyball players are not necessarily good at playing football. Although there are similarities, there are differences in concept after all.
Strength weightlifting has three events: hard pull, squat lift and chest muscle, all of which are done with barbells. The rule is: whoever can make a complete movement with the heaviest weight will win. It is conceivable that it pursues neither beauty nor flexibility, but absolute strength, which makes them have to keep some body fat for high-intensity training, so we can see that.
This habit of only looking at the "front" is also very common among novices, and is called "Mr. Mirror Bodybuilder". He doesn't practice what he can't see in the mirror. Of course, knowing a lot of comprehensive old guns has also taught me a lot of experience, just saying that this phenomenon often occurs in an era when fitness knowledge is not yet universal. Don't make this mistake when you go to the internship.
Running is a great fitness program, which can exercise your strong cardiopulmonary function, but it also brings some problems, such as muscle consumption, knee wear, foot bone strain and so on. So, although running is good, don't drink too much! Don't run with the mentality that whoever stops first will lose.
However, if you often go to the gym, you will know that not all foreigners are muscular men, and it is common for white and thin young people with dirty braids to lift iron in irregular positions, so please put aside the idea of "racial talent", which is all learned and practiced.
Fitness is just a personal hobby.
Some people like it, others don't.
This is normal. There is no need to crowd each other out. It is also brainless for bodybuilders to despise people who never exercise. They think people who don't exercise are too good to do so. They think people who don't exercise are lazy and have no quality of life. They never consider these so-called "lazy" people, people who have no fun in life, not because they don't want to go to the gym, but because they have no time, need to work to support their families, accompany their families or have other higher activities.
