How to grasp the breathing rhythm of freestyle?

The breathing rhythm of freestyle varies from person to person. The key is to find a rhythm that suits you.

According to your description, the rhythm of six strokes and one breath obviously doesn't suit you, and I think most people don't. Because you are in a state of holding your breath, in this case, the blood oxygen content drops rapidly, then you have to breathe every four strokes, and then you have to breathe every two strokes.

So the factor to consider is how far do you want to swim at once? If the distance is 50 meters, 100 meters, then you can swim 50 meters in six strokes or even in one breath! But if you want a long distance, more than 500 meters, then two strokes and one breath are the most appropriate, so that you can better achieve the combination of physical use and speed pursuit.

The second factor is the pursuit of speed. If you want a faster speed, you can only reduce the number of breaths. And if you want to swim smoothly, you can increase the number of breaths, so as not to hold your breath and cause your physical strength to drop too fast.
