How did it happen

As you will discover, most injuries that do not involve someone or something else are usually because the victim is poorly trained or in my case overtrained. The term "overtrained" refers to someone who has worked out too long, too frequently or both. In my case I had been training the Olympic lifts and squating three days a week nonstop for about eight months before I noticed anything other then fatigue. Well that anything other was what should have told me I needed some time off. There is a term in training called "periodization". It means to vary training volume, intensity and frequency. It also means taking a week off in my case every ten to twelve weeks. Dr Stuart McGill has a great illustration of this phenomenon in his book "Low Back Disorders" on page 13 figure 1.2. This illustrates the "overtrained" injury sequence perfectly. Thats how mine happened.
