When I started to learn how to swim, the swimming instructor
told me the correct technique for freestyle is very relaxed and not
making a lot of water splash. But the problem with this style is
hands and legs muz co-ordinate which I cannot. So in the end I
focus on frog style cuz when I kick my legs my arms is straight no
action. When my arms pull up to take a breather, my legs is
stagnant. It is like when I use arms I no use legs. When I use
legs, my arms is juz set straight. I find out I can last more laps
this way.
Of cuz free style experts may differ. Those into competitive
swimming is of a different genre as they focus on speed and breath
which is out of we leisure swimmer league IMO
