This may be a dumb question. Most of the clients at the gym I frequent have trainers. Some people do active stretching exercises, others are passively stretched, that is the trainers do most of the work. I've always done the active kind, but recently my trainer was out of town and his substitute, who just got his doctorate in PT and leaves soon to set up a program in a major university, did my stretching for me. He offered the verdict that my hamstrings were too tense, too short, or too something or other. He also said that I really needed to work therapeutically at this point more on increased flexibility than on increased strength. My trainer agrees--and in fact he had suggested the passive stretching exercise while he was gone.
I suspect there's a whole lot here that I know nothing about. I've worked for three years now on improving strength, stamina, and to some extent balance. But what about flexibility.
