I was perusing my copy of Science of Sports Training this evening and ran across a training principle which many, many trainers and coaches fail to follow. It is called The Principle of Economy of Effort. In a nutshell it states that a training program should be constructed such that the desired outcome is achieved with the least possible training load. The principle therefore protects the trainee from overtraining and injury thus promoting lifting longevity and overall progress. This principle applies to load intensity, training frequency and volume.
Heed this principle in your training no matter your goals and you will be the better for it.
