Anyone can sink, the key is to master the skills yourself, and you will be able to walk on the water.
If"Lie down"On the water, most people will sink, and the same is true for good swimmers. If your goal is not to sink, take a float, grab the front end of the float with both hands, push your feet up and forward at the same time, try to make your body float, if necessary, you can find a friend to assist, slightly support your abdomen, at the same time don't stiffen your body, let alone gather all your strength on the float in your hand, it just plays a guiding and auxiliary role, if you press it hard, you will never be able to float.
When you can easily float with the help of the float, just learn the swimming movements of the feet, if you don't take the float, I'm afraid you will sink because you are too nervous, if you have the basic movements of the feet, even if there is no float, you can also support in the water for a period of time, at this time you can train to paddle with water.
When you can coordinate your hands and feet, you can float on the water even if you don't paddle, because you are already familiar with the water and will not be so stiff anymore.

For the problem of playing water with your legs, you can ask others to hold your head with one hand first, and then you can float your whole body on the water as much as possible through your legs, and find a feeling, and you can float on the water without others supporting you after being proficient.

Don't jump your whole body, and don't move your legs first Keep your body straight in the water Points: The head must sink a little bit, and the consciousness must also sink a little bit, so that it will slowly float from the bottom to the head, remember, don't jump

Take a breath in and the average density of fluids in your body will be slightly less than that of water, so that you can keep your neck muscles relaxed and float.
-
The body must be very relaxed to float.
-
When the human body is relaxed, the muscle density is the same as water, and when it is nervous, the density is greater than that of water. So just relax.
You can try to pull the wall of the pool first to feel the feeling of floating, and then you won't be nervous.
-
I also just learned, others taught me to relax, and then I tried it, it is true, the most important thing is to let yourself be completely relaxed, if you can't float, it can only mean that you are not relaxed, and you have to practice more, you can first hold your breath in the water to let yourself float, come long, no problem, believe in yourself, ok?

There is a coach in the easiest to get, if not, first learn to hold your breath, and then relax your whole body to hold your hands on the shore to let your body float, so that you can find the feeling that you can't fall, so that you can overcome the fear of the psychology of learning not to be timid, and then hold the shore to practice swinging foot movements, and then learn to breathe, ventilation is the most critical, exhalation and inhalation are done on the water, don't exhale underwater, it is easy to inhale the water, exhale and inhale is done at the same time, remember to exhale to open your mouth wide, Otherwise, the qi will not be sucked in automatically. Learn to breathe in the end is the hand, learn to be very blocky, there is a coach for half a month, no coach, according to mine, 20 days to become, the action is learned, more days to swim faster speed!
It should be done on the water when ventilating, and the exhalation should be done at the same time! When exhaling, open your mouth wide, otherwise you won't have much air to breathe in.
So why can't you exhale underwater: I think it's easy to suck water into your lungs when you exhale underwater, and it increases the resistance when you exhale underwater!
It's the same for every swimming style, do it!
