Executing an open turn efficiently requires a few precise steps. As you approach the wall, perform a final stroke and kick to set up for the turn. Reach out with one arm to touch the wall; as you do so, rotate your body to face it.
Push off the wall with your feet while completing the rotation, and transition smoothly into the new direction. Focus on maintaining a streamlined position immediately after pushing off to reduce drag and ensure a smooth continuation into your next stroke.
