#218--Weight training is intense. Well, it's not the way many people do it, but it should be. So as a person gains in strength, the program he or she follows needs to be changed more often to keep the body from being exposed to repetitive trauma. And the reverse of this is true, as well. In the early stages of development, someone can be exposed to the same exercises more frequently due to the relatively lighter loads/intensities employed. As the person's level of proficiency allows for greater and greater loads and/or volume to challenge the body's increasing levels of strength, a larger variation in program design as well as increased rest intervals are essential to keep the gain without the pain.
