It's the only stroke you do on your back. No wonder it's called backstroke. Duh. It's basically freestyle on your back. The arms alternate in and out of the water pulling one at a time. The kick is a flutter kick just like freestyle only your feet are upside down.
Backstroke is a great recovery stroke. The DPS (distance per stroke) is the longest in back stroke. You go the farthest with the least effort. Also since your head always remains out of the water, you can breathe constantly. The more you breathe, the faster your muscles recover. When you get tired backstroke is a good idea.
One major flaw I've seen in people just learning the stroke is body roll. Every time a hand enters the water to start a pull, you should roll onto that side of your body. This will lengthen your stroke by 2-3 inches every time with no added effort. When you have 20 strokes every 25 yards, that's a big deal.
Another thing is the placement of the arm during the pull. Your arm should enter the water perfectly straight. From there, your arm should bend at a 90 degree angle so your hand is pointing directly away from your body. From that 90 degree angle then you throw your hand towards your feet as hard as you can. Then you simply recover out of the water and start over.
One big thing the pros do better than us is their ability to recover their arms very fast. That means their arms spend very little time out of the water. They spend more time pulling and less time recovering. There arms aren't symmetrical (they never make a 180 degree angle). The great swimmers' arms are often both in the water pulling at the same time(one finishing the pull and one starting). Two arms pulling means they go twice as fast.
Their start are also amazing. Take 26 seconds out of your day to watch this.

I'll talk about starts in a later blog! Next week, breaststroke.
