Kets, not sure if you are with me or not in my explanation, your two posts are polar opposites. I agree with what you are saying; variety is key to maximizing potential, no doubt there. I am saying that I see MANY guys in the gym training partial ranges ALL DAY, EVERY DAY, I am just providing the science behind partials, when they are beneficial and when they are not. I'll tell you, 95% of the time, they are NOT being utilized correctly.

And when I say full-range, I do not mean to the point of hyperextending the elbow, I simply mean bringing each and every muscle through the largest and safest possible range of motion. This will yield the greatest adaptations in muscular hypertrophy.

Here's the key: If you DO train your full range of motion, and then decide methodically that you want to add some partials into your routine, I think that's OK.

I am NOT saying that there is only one way to train, however I am saying partials are not the best strategy for hypertrophy training, but there's nothing wrong with throwing them into an already sound training program.
