1, don't go hiking.
Many friends often like hiking, that is, swimming in unattended puddles or rivers. In fact, this is very dangerous. Accidents happen in these places every year all over the world, so for our safety, try not to go to these places to learn swimming. My suggestion is not to go to these places at all, because people who swim well will drown and often get close to dangerous places, and something will happen sooner or later.
2. Try to find a coach.
If we are beginners and want to learn swimming, I suggest you try to find a coach to teach us, because there are many ways to swim. If we don't have a good coach to teach us at the beginning, it is likely that our swimming standards will be particularly irregular, which will not only look unsightly, but also be particularly inefficient.
3. Learn to deal with emergencies.
Finally, before learning to swim, we must learn how to deal with emergencies, for example, what should we do after leg cramps during swimming? Or what should I do if I drown because of some special circumstances while swimming? Wait, wait, wait.
