1, kick board, in fact, this equipment plays a vital role in learning to swim. Generally speaking, the proportion of kicking practice in the initial stage should be relatively large. Some swimming pools will prepare a public kick board for everyone. If you want to choose by yourself, I suggest choosing a triangle or an I-shaped one, because you can directly be a figure-of-eight board and practice rowing with your legs later, so that one thing can be used for multiple purposes.

2, draw the palm of your hand, put it on your hand and paddle to strengthen your arm strength, suitable for middle and senior enthusiasts. In the choice of size, it can be slightly larger than your palm. Don't buy a big one. You don't have enough strength to row, and you are easily injured.

3, 8-shaped floating board, sandwiched between the legs, to provide a certain buoyancy for the lower body. When practicing, hold the figure-eight floating board with your legs still and paddle with your hands, usually with your palms.

4, flippers, an auxiliary tool when practicing freestyle legs or butterfly legs, used to enhance leg strength and find the feeling of walking water. Please note that you should swim with fins instead of diving. There is an order of magnitude difference between them.

5, breathing tube, so that swimmers can always swim with their heads down, without spending energy worrying about breathing problems, mainly practicing freestyle swimming, especially the balance of swimming. There are also two versions of this one, the diving version is on the side and the swimming version is on the front.

6, resistance pants, generally only quasi-professional, professional or super-fever enthusiasts will choose equipment. Covered on the outside of ordinary swimming trunks, the surface is composed of many net bags, which increases the resistance in water and is one of the most abnormal equipment.

7. Tension rubber bands are divided into land and underwater. The ground is called a tension rubber band, and the terminal is fixed somewhere, which is mainly used to practice arm strength. What is in the water is called underwater traction, one end is fixed, the other end is tied to the waist, and then you swim forward.

8, metronome, good rhythm has a great effect on swimming speed. This gadget can make a ticking sound according to the number of minutes. When swimming for a long distance, you can adjust the stroke frequency according to the standard rhythm. When you are tired or want to be lazy, the sound of dripping water can also play a warning role, urging yourself not to relax and keep up with the rhythm. You can also use this to master the rhythm of running and set the sound to the pace frequency.
