If you want to do something good for your health, swimming is recommended. However, there are a few things to keep in mind:
1. Not a substitute for strength training: although swimming uses various muscle groups, the buoyancy force reduces the resistance against which the muscles have to work. It is therefore primarily an endurance training, which is ideally supplemented with strength exercises.
2. Breathing correctly: Sounds banal, but it is one of the most common mistakes in swimming. Breathing should always be in harmony with motor activity, otherwise there is a risk of side stitching, for example, and performance will be reduced. In a swimming course, in addition to the correct movement sequence, the appropriate breathing technique is also learned.
3. Posture: a stiff neck is common in breaststroke swimmers. In the early stages, people tend to keep their head permanently out of the water and throw it backwards. In the long run, this can cause pain in the neck and upper back. Also with other styles the correct body posture is not to be disregarded, therefore a swimming course is likewise offered with beginning ambition, in order to avoid such typical errors and to have durably fun with the sport.
