A man with these lines on his body must be a successful person

Many fitness enthusiasts think that muscle training is only for athletes or bodybuilding enthusiasts and is not necessary for ordinary people. In fact, basic muscle training is good for everyone. Muscle training does not necessarily have to be for the purpose of participating in bodybuilding competitions or having a body like a professional bodybuilder. Because good muscles are an important element of physical fitness. Many women have always believed that weight training will make their muscles more masculine. In fact, this worry is unnecessary. Since women have less male hormones and muscle fibers than men, it is extremely difficult for them to develop muscles as developed as men.

Muscle training can increase muscle volume and strength, which is beneficial to sports performance. The chances of injury to muscles, tendons, ligaments and bones are also lower. Good muscle strength has a better protective effect on the joints of the body. More importantly, it can help maintain the correct posture and relieve the discomfort caused by long hours of work and study...

Basic knowledge of human muscles

Muscles are important tissues in the human body and play an extremely important role in sports. The human body consists of two types of muscles: voluntary muscle (or skeletal muscle) and involuntary muscle. Such as the muscles of the digestive system and the heart muscles. The muscles involved in movement are mainly voluntary muscles. Because when these muscles are contracted under conscious control, they can cause the body to move. The human body has about 434 skeletal muscles, which are composed of 25 billion muscle fibers and account for about 40% of body weight.

In addition to genetic factors, exercise and dietary nutrition are also very important for muscle development or hypertrophy. The most effective method of exercise is weight training, also known as bodybuilding. Muscle ability includes strength, endurance, flexibility, explosive power, speed, balance, agility, etc. When it comes to healthy physical fitness, muscle strength and muscle endurance are more important. For sports, other abilities are important.

Muscle strength refers to the maximum force that a muscle can generate during a single contraction... Muscle endurance refers to the ability of a muscle group to perform repeated contractions or maintain static contraction for a period of time, such as long-distance running. The purpose of participating in bodybuilding training is to pursue developed muscles and make the muscles even and well-proportioned. The focus of bodybuilding competitions is on the participant's muscular development, the distribution and proportion of muscles throughout the body, and the beauty of lines.

Bodybuilding training effects

Long-term bodybuilding will cause the following changes in the body:

(1) Muscles become enlarged and thick. This can increase the muscular beauty of men, while women will have firmer and more elastic muscles. Increase the beauty of lines. Women have fewer muscle fibers than men and more female hormones in their bodies, which hinders the development of muscles.

On the contrary, if muscles lack exercise stimulation, they will atrophy. The most obvious example is after an injury, after a long period of rest, the lack of exercise in the muscles will become loose and shrink in size. However, developed muscles will not turn into fat as some people worry.

(2) The volume and flexibility of the ligaments increase. This can firmly protect the joints and reduce injuries

(3) Increase muscle contraction strength, speed, endurance and explosive power, which can improve athletic ability.
