Hello,

Thanks for the post ElPietro! Great info. Yes, I believe you did misunderstand. As you know it can be difficult to discuss some of these issues and not write text books for each post. So I try and keep my words to a minimum. Thus, misunderstanding’s occur.

My quote was referring to two different muscles: the pectoralis major and pectoralis minor. In most theories muscles act on a “all or none” principle. That is, muscle fibers either contract or they do not. They do not know how to contract half way. The more strength is needed the more muscle fibers are recruited to perform the lift. Both of those muscles are not recruited in the same ways at the same time. But , if you are talking strictly about the pectoralis major (singular muscle) then of there is no such thing as isolation.

However, in performing the bench press, the pectoralis are not the only muscles involved and in the lift. So at various angles and grips the triceps and deltoids can play a greater or lesser role in the lift.

Thanks.

wushu chik,

Sometimes, that doesn’t mean jack. You should have seen some of the people who were at the last IDEA conference in San Francisco. In particular was a woman who got winded coming up one flight of stairs, about 275 pounds, telling everyone who would listen that she was a certified trainer/nutritionist. And I won’t even mention all the “Lifestyle Management” certificate folks…yeesh.
