Is the “S” Pull Still a THING?

As far as a pulling pattern is concerned, when I was younger, they used to teach the S pull, the keyhole pull. They don’t do that anymore, because the more research they did on fluid dynamics, the more that they saw that if you did an S pull it doesn’t add lift to a swimmer, they don’t like lift doesn’t happen in water. The forces of lift, so pulling straight back is the quickest way to get a swimmer from A to Z. So, the middle finger enters right in the respective shoulder and you pull straight back past the hip. That’s the ideal pulling pattern, there’s no sort of crazy S pull there are no super-wide pulls we want to avoid crossing over. You just want the hand kind of right outside the body going straight back past the hip.
