Building on from push and glide, understand where your body slows down and then start kicking. Keep great form and tension in your upper body to help you soar. This is a great way to work on your kick too - keep your legs strong and your kick small but powerful, kicking from the hip. Challenge yourself to see how far you can go. Take it to the next level and feel the speed trying it with fins too. When you run out of breathe you can stop and run back to the start or start swimming to the end of the lane. Enjoy it.
