1, breathe:
How to master the correct breathing method is the key to learning to swim. Breathing in water is mainly divided into inhalation and exhalation. Keep your head down after inhaling. When swimming, don't inhale immediately and then spit it out. When exhaling, swing your arms, then paddle your hands forward, kick your legs out of the water and inhale, and so on.
2, breathing rhythm:
Breathe regularly and rhythmically when swimming, and exhale through the nose and mouth in the water. In addition to paying attention to the rhythm, you can also cooperate with the action of pressing water with your hands.
3. Balance:
To make the center of gravity of human body coincide with the floating center, people should be on a straight line, which is called the longitudinal axis of human body. The head, shoulders, chest, waist, hips, legs and feet should be on the longitudinal axis of the human body, and when the arms are stretched forward, they should also be on the longitudinal axis of the human body; Secondly, press the chest to make the floating heart move backwards.
Step 4 relax:
Relax when swimming, try to reduce your exertion as much as possible under the premise of moderate tension or moderate exertion, and don't change your body when you exert yourself. You should grasp the posture of your body and keep relaxed.
Swimming includes freestyle, butterfly, backstroke and breaststroke. No matter what kind of swimming, your focus is 3 o'clock 1 line. Your waist must be straight, so that you can swim faster. Your latissimus dorsi is stronger, or your shoulders are stronger, and you will swim faster. More is our latissimus dorsi teres major, with greater force.
