Low profile breathing swimming workout

A lot of swimmers, especially young ones and beginners, tend to rotate to much or they rise their heads up while breathing in freestyle. Swimmers who do that mistake lose balance and they don't swim straight which leads to neck pain and loss of speed. We all know that the better the technique the better we work out. With that in mind, I'll post various swimming workouts that will help you improve your swimming technique as well as challenge you aerobically. If you have any questions about the workout or the format that I'll use to write it, please make a comment or pm me.
