Some of those techniques came to haunt me a few years later, when knee and back problems permanently limited my training. Today I promote a conservative approach to training in general, and to exercise selection and technique in particular. Experience has taught me that the conservative approach is not only the safest way, it is actually the most productive and satisfying, over the long term. The conservative approach is not just limited to exercise selection and technique. It also concerns exercise program design.
Most people train too much.
1.71 All this assumes that you actually keep training over the long term. An obsession leads to burnout because it produces poor results for most people. It causes so much frustration that most people give up training after a year or few, or they turn to drugs. When you are obsessed you tend to discard reason and intelligence, and become all passion and emotion. This leads to gullibility and following poor training programs, skewed diets, bad exercises, and destructive ways of performing exercises that should be safe and super productive.
