The timing of the protest continued to change because

1. Learn how to breathe. Take deep breaths and breathe out underwater in a slow and controlled way. Don't blow out to complete exhaustion - instead do it in a comfortable way, staying relaxed and controlling any anxieties.

2. Practice gliding across the water. Push off from the poolside and get a feel for your efficiency through the water. Experience the feeling of slowing down and slowly sinking, and then use gentle arm and leg movements to slow down or prevent sinking. It is important to move in a relaxed and controlled way, without any panic.

3. Learn how to submerge. Discover how your body moves when it is completely underwater and get used the feeling of the water allowing you to move rather than resisting your movements.

4. Learn how to float. We all know that some of us float well and some of us simply do not - but we can all remain at the water surface one way or another. Be it naturally floating or using some form of swimming to stay there, feeling your way through the water and not fighting it is the essential mind set here.
