Swimming lessons give a budding swimmer a lot of solid techniques.However, most swimming classes are slow because they focus on teaching the techniques first before showing how to float. Some individuals take small approach so that they can overcome the fear of water and then speed up the process greatly. In swimming when it feels tough then you are doing it right.
After that we just need to do the "jellyfish", and then apply the strokes that we have learnt. And we will see ourselves moving forward in the water!
