Quoted message said:I have a question on what this particular exercise is called:
Like when you tense up opposing muscles so your arm doesn't move so you can
show off your biceps. It's like isometrics, but you aren't pushing against an
object and you aren't pushing against your own hands. You are using your own
muscles to do isometrics. Is there a special name for this? Other than
"flexing" ; )
Ok now take that same concept of flexing, except you move through your entire
range of motion. How would one categorize this specifically? Isometric?
Isotonic? Isokinetic?
Another form of this exercise is flexing while lifting. That is, to flex your
muscles while lifting in order to gain more conscious control of the muscle
contraction.
Are there any books/videos/research that discuss this?
Thanks,
Lou Stein

"It's called isokinetic exercise.It's like isometric but with
movement."
Maybe I'll learn something here.
I Googled this very briefly and came across two different descriptions
of isokinetic. One involves contracting and shortening the muscle at
constant speed. The other is sometimes called "accommodating
resistance exercise" and entails maximum muscle contraction throughout
the full range of joint movement. "Resistance is variable in
proportion to the change in muscular capability at every point in the
range of motion. The variation is controlled so that at all times it
equals the product of the muscular strength." In either case, it
seems that machines (Norm, Cybex) are needed to do it.
I'm not exactly sure why this has been touted as
"the fastest way to increase muscle strength".

Isn't "flexing while lifting" another way to describe getting and
staying "tight" while lifting? So why is moving a free weight through
a full range of motion while staying tight a less efficient method of
gaining strength than using machines to do isokinetic exercises?
