To be safe in the water you don’t have to be the best at swimming, you just have to be able to keep yourself safe. Which means being able to float and swim away from any dangers if needed.
The easiest thing to do is the doggy-paddle, but this can use a lot of your energy. Backstroke and freestyle are another two style’s of strokes that are quite easy if you think about it. They’re basically floating, but adding the movement of your arms and feet. If you are in some sort of danger, it would probably easier to flip onto your back and swim away.
When moving your arms in backstroke, it’s like painting a big line across the ceiling or sky. And all you do with your feet is kick tiny kicks just under the surface of the water. So it doesn't create a huge splash.
Another thing to do is when you bring your arm under water, create the shape of a ‘S’ by swivelling your hand.
And finally, when swimming we have to keep in mind to have your eyes up. Try not to look around at our surroundings, it prevents you from sinking.
