Underwater Dolphin Kick is a skill worth mastering, even if you do only one or two dolphins at the start of every length.
Push off in streamline and immediately start to exhale through your nose. Round your back slightly, point your toes, and start a dolphin kick that begins at your sternum and travels down through your toes.
If you need air, simply aim your fingers toward the surface and your body will start to rise.
