You feel it more because it is a movement that provides the greatest resistance in that contracted position. It's that contraction you feel but does it train the muscle optimally? Unlike Bhanks, I never trust my "feelings" in anything in life. I trust reason. An analogy would be the leg extension versus the squat. You can really feel those quads after a brutal set of full contraction leg extensions, there have been times when I even cramped up. With squats, you can never achieve resistance in the fully extended position. But do you think you can optimally develop your quads doing just leg extensions as you would doing squat type movements?
I agree 100%.
A "feel" doesn't mean much. I can get an incredible pump and feel doing pushups and cable flyes, but my chest isn't going to grow much.
Same with leg extensions.
There is way more to this, but i'm honestly not much of an expert on kinesiology. I just lift heavy and as intense as possible.
It is an interesting subject i'd like to know more about.
