Step 1
Perform the flutter kick to propel yourself with your legs. The kicking motion will remain constant throughout your swim. Keep your knees slightly bent and flexed, and move the legs back and forth opposite of one another, keeping your feet outstretched to use as flippers. Avoid bringing the feet out of the water as you kick.
Step 2
Place both of your arms straight out ahead of you, parallel with the water. Keep your head down to reduce drag resistance.
Step 3
Bring your left hand down through the water, flattening your palm and facing it in the direction the arm is moving --- this will maximize how well you pull your body through the water.
Step 4
Bring your left arm out of the water, keeping your head down. As the arm exits the water, bring your right arm down through the water in a motion identical to that of the left arm. Your right arm should arrive all the way back, parallel with your legs, as your left arm moves to the front and enters the water straight out ahead of you once again.
Step 5
Repeat this motion continuously so that the arms are always opposite one another --- at any point you should have one arm in the water and one arm out of the water. Keep your head in the water and slowly exhale. When you need to take a breath, turn your head to the side of the arm that is raised out of the water and breathe in quickly -- do not crane your neck to get air, as this will break your streamline in the water. Breathe only as often as is necessary.
