In other words, to make the training functional for a targeted movement or technique. As you know it’s rare that an athlete performs the same skill with both arms/legs at the same time. A ball is thrown with one arm at a time, by a soft ball player. A kick is executed with one leg at a time by a combatant or a soccer player. A handball player slaps the ball with one arm. It only makes sense to train unilaterally if the circumstances allow it.
The other reason for one sided training is gains in strength. Most people who see pushups, rows, squats and other exercises as primary endurance training, won’t say the same about unilateral variations of the same exercises.
The goal of this book is not only to explain how one can convert two legged/two armed skills to one legged/one armed skill. The book actually guides you through the five steps needed to master a unilateral skill.
