Lie flat on your stomach and extend your arms and legs. Begin by moving one arm in a circular motion, as if you're reaching out to scoop water towards you, then push it back. Do the same with your other arm in a rhythmic motion.
Kick your legs up and down in a flutter kick motion, keeping them straight and close together, while alternating your arm strokes.
Turn your head to the side every few strokes to breathe, making sure to exhale underwater before you turn your head to inhale.
Continue this sequence of arm strokes, leg kicks, and breathing for the duration of your swim. Always remember to maintain a steady, rhythmic pace to ensure you can keep swimming for longer periods.
