“Let me give a little background on Dr. Lederman. What he is speaking
about is a specific technique of core activation that targets two
muscles in isolation, that is the lumbar multifidius & the transversus
abdominus. The techniques involve pressing your lower back into a
specialized pressure cuff, and sucking your belly button in in
different positions- guided by ultrasonic imaging. This is popular is
some physical therapy clinics that specialize in back pain.

He is not speaking of core training in general. Mykael reminds us
that core training should be “purposeful”. That is, if an individual
is involved in an activity which requires them to get off their back
in a hurry (police, wrestlers, military etc) then a good percentage of
their time should be done in horizontal floor. We can even take that
concept a step further and say if this athlete might take a blow to
the mid section (football, boxing) then some isolated ab training may
also be considered “purposeful”.

However, when we speak of upright function, the role of the core
changes into one of integration & coordination of the upper & lower
extremities. If you follow my blog, I suggest the concept of
“reactive core”. (You can visit Joe’s web site at http://joestrainingroom.blogspot.com/) I have a problem with the “rigid pillar” concept
that Verstegan et al speak of. I prefer the idea of the core being
reactive to high velocity changes of arms & limbs (sprinting, throwing
etc). Here different types of skips (such as Hans Boche advocates)
and jumping jacks can be considered “core ready” exercises.

It this situation, when we decide to return to the floor, we must be
sure we are getting something that we can’t get upright. Vern
Gambetta recommends, in these athletes that no more than 10% of their
core training be on the floor. I’m not sure where he came up with
that, but clinically I think it’s right on.

It is amazing to me that I’ve read the exact same books that Mike
Boyle has read, and have come to different conclusions. But yes
Makael, he has produced.

Clearly from this passage and from the reference to the principle of specificity Professor Lederman says exactly what you are saying. The example of the MMA fighter is addressed with the recognition of this principle. And with few, valid exceptions in the athletic world and for the average Joe, working the core while kneeling or lying down is in fact useless. And keep in mind the words of Vern Gambetta, all work is core work.

To the point about the ab wheel, performing it from a standing position is more difficult than from a kneeling position and therefore, IMHO, has more functional value regardless of who is doing it.

Thanks for participating in the dialog!
