There are three different styles of breaststroke being swum today; the wave style, the flat or conventional style and the undulating style. Author explains the modern breaststroke swimming technique. What he does recommend is a modified flat or modified wave style, using the wave's base position as the starting point. This base position is with the body flat in the water, streamlined. The head is between the arms, starting to go underwater with the back above the waters surface. The back is out of the water to eliminate lifting water up with each stroke, one of the disadvantages of the undulating style. Author explains the phases of the technique and drills for the arms and legs.
