Learn from me in CCTV freestyle. Very detailed, the world champion will demonstrate.

I'm a swimming coach. I take a breath with my head sideways. The method is: when paddling alternately with both hands, when paddling to the waist and lifting off the water with one hand, the body relays to one side and turns to inhale quickly. At this point, the other hand tries to move forward, not moving, and is controlled in the water.
