Compared with many fitness methods, dumbbell exercise is convenient, economical and practical. Convenience is reflected in that it can be done anytime and anywhere; economy is reflected in that it can save the cost of card application compared with exercising in the gym; practicality is reflected in that it can exercise muscles in all parts of the body in an all-round way.
Comprehensive physical exercise
Dumbbell movements are mainly arm movements, so many people mistakenly believe that dumbbells are only suitable for exercising upper limbs. Dumbbells are indeed a good tool for exercising arms, such as the biceps and triceps of the upper arm and the deltoid muscles of the shoulder. As long as the exercise method is changed, these muscles can almost be exercised with dumbbells. But using dumbbells can also exercise muscles in other parts of the body, such as dumbbell flyes can exercise chest muscles, dumbbell rowing can exercise back muscles, seated dumbbell Russian rotations can exercise waist and abdominal muscles, various dumbbell squats and lunges can exercise lower gum muscles... As long as you master the method, a pair of dumbbells can exercise the whole body.
Enhance muscle strength and endurance
Dumbbell exercise is mainly to enhance muscle strength, and it also helps to enhance muscle endurance. Exercise with dumbbells is a typical weight training. Appropriate weight can stimulate muscles to a certain extent, improve the ability of nerves to recruit muscles, and increase muscle volume to achieve the purpose of strengthening muscle strength. In the process of resistance training with gradually increasing load, muscles continue to adapt to greater exercise loads. While muscle strength is enhanced, endurance is also enhanced, so that muscles can continue to exercise for longer under the same load.
Beneficial to fat loss and body shaping
Regular weight training can increase the muscle content in the body, improve the basal metabolic level in daily life, consume more energy, and achieve the purpose of fat loss. At the same time, increased muscle volume can also improve body shape and achieve the purpose of body shaping.
Improve health level
During exercise, the human body's circulation, breathing, and nervous systems are all involved. During exercise, using dumbbells to increase the training load will stimulate these systems more, and in the long run, it can effectively improve the body's health level. The following briefly introduces the changes in each system during exercise.
First is the circulatory system. During exercise, the heart rate increases, blood vessels dilate, blood flows faster, and body temperature rises. Exercise enables the heart to work better in an oxygen-rich environment, increases the strength of the myocardium, and can supply more blood with each contraction, thus strengthening the function and ultimately improving the circulatory system.
The second is the respiratory system. During exercise, in order to supply more oxygen to the muscles and expel the large amount of carbon dioxide produced in the body in time, the organs of the respiratory system begin to work hard, and the respiratory muscles actively participate in exercise, which increases the amount of gas inhaled and exhaled, which means more oxygen inhaled and more carbon dioxide exhaled. In this process, the functions of the organs of the respiratory system are improved.
Finally, there is the nervous system. The nervous system can control muscles and regulate the rest of the organs and systems of the human body, enabling people to complete various complex activities. During exercise, the blood supply and oxygen content of the nerves can be improved, the control of the nerves over the muscles can be improved, and the coordination and accuracy of the movements can be improved.
Reduce the cost of fitness
Dumbbell exercise does not require a large venue or a lot of money, which greatly reduces the time and economic costs of fitness. Even if you don't go to the gym, you can find a small open space at home or in the office to train.
Dumbbells are mass consumer goods, and it doesn't cost a lot of money to buy dumbbells. Trainers only need to choose dumbbells of appropriate weight according to their actual situation. Even if they buy a few more pairs of dumbbells, they do not need to spend a lot of money.
