- Sweep out, with fingertips down, and FLEX during the pull/insweep. Flex muscles to "pull/catch/grab" as much water as possible.
- During the recovery, you should be stretched out and somewhat RELAXED for the glide aspect of breaststroke.
Try thinking about flexing your muscles as you pull, and relaxing your arms, while staying lengthened, on your next breaststroke set.
Best of luck!
