Can someone explain this exercise?

Post by paul_k » Wed Mar 19, 2008 9:49 am

http://www.exrx.net/WeightExercises/Del ... Raise.html

and particularly why it does train the serratus anterior ?

From this link (http://www.exrx.net/Muscles/SerratusAnterior.html) you can see that Serratus anterior moves the scapula away from the spine, around the thoracic cage and rotates it upwards.
In this exercise the weight facilitates this move down so SA does not have to work and move the scapula away from the spine or is it something else that I don't understand?

please help.

It doesn't, the serratus is just a synergist.

I think you were looking for something like this:

The SA has to work to keep the Scap close to the rib cage...

i.e. the link you posted to the SA page says,
The serratus anterior holds the scapula against the thoracic wall
It's an often overlooked part of, erm, muscles - not only do they CREATE movement, but they also RESIST movement.

On the same note, Stability is defined as "The ability to resist undesired movement"
