This is a great drill to learn about timing and to teach swimmers to use body rotation to achieve optimal breathing position. Other areas that are promoted in this drill are a strong core position and the importance of the kick with regards to timing to create forward propulsion at the time of breathing.
- Little pause at the back as you breathe - you don't want to be pushing straight down on the water with your lead hand to create your breathing position.
- Rotation is key with timing
- Kick consistently
- Strong/ tall body position
