What muscles does swimming exercise?

Swimming can effectively exercise the muscle tissue of the whole body and make the skin smoother and more elastic. Not only that, the lung capacity of swimmers is much stronger than that of normal people, and swimming can also promote the improvement of myocardial function. Swimming has been one of the main ways for humans to exercise since a long time ago. There are many specific ways to swim, such as breaststroke, butterfly stroke, etc. The following introduces which parts of the body's muscles can be exercised by swimming.

Breaststroke, leg strength. The thigh movement method for freestyle and backstroke is to whip up and down, only breaststroke uses kicking and clamping. The former can make the legs longer, while the latter uses the quadriceps femoris more, so it is very effective in strengthening leg strength.

Butterfly stroke, chest strength. When doing butterfly stroke, the arms paddle inwards, similar to doing chest expansion exercises. It puts more force on the pectoralis major, dorsal dilators, and rectus abdominis, and has the best training effect.

Freestyle, arm strength. When swimming freestyle, the biceps and triceps in the upper arms use more force, which can effectively exercise the arm muscles and also has a certain effect on improving the strength of the shoulder muscles.

Backstroke, back strength. When doing backstroke, the back expanders will exert more force, which can stretch the back muscles. In addition, when doing backstroke, you need to lift your hips and glide, which is also a kind of exercise for your buttocks.

You can choose your favorite swimming style and focus on strengthening the strength of a certain part of the body, which can also improve your swimming speed.

When swimming, stretching is not only a good warm-up exercise, but also the best relaxation exercise after swimming. It can protect you from sports injuries such as cramps and strains caused by swimming, and can also relax tense muscles throughout the body. The same applies to stretching as in other exercises.

Swimming can not only exercise people's muscles, but also increase the body's ability to withstand cold. When swimming, the skin comes into contact with water and the skin capillaries will contract. Since the water temperature is lower than the skin temperature, frequent swimming will enhance the skin's ability to adapt to the temperature and thus improve the cold resistance. This is why some people can swim in winter without catching a cold.
