Contrary to what you might imagine from watching the straight arm recovery over the water, the pull in
backstroke is nothing like a windmill under the water. In fact, the elbow should remain deeper than the hand and have a
considerable bend in it. Overall the arm action can be separated into three distinct phases:
1. The catch. A common backstroke error is starting to pull before you’ve got anything to pull against. So when you’ve put
your hand in pause for a second. Could you reach further down the pool by rolling onto your side? (as long as you don’t turn your
head, but keep it still and looking upwards, the further you can roll the better).
Also, is your hand a good 10 cm under the water and turned at the wrist ready to pull?
