Function of the Core....
Geoff Neupert proposed this for the function of the core: 1. Produce non-compressible cyclinder to protect the spine against external load; 2. TRANSMIT force via rotation, etc.
I countered with the idea that I feel the job of the core is to prevent rotation/movement not produce movement.
Then Geoff and I spent some time on the phone and discovered that we were a lot closer on things than these two statements would appear.
When you get into a debate of semantics and internet one dimensional statements a lot can get lost in the process.
Geoff pointed out that the lumbar spine can and should rotate as it is designed to do and should do as a part of normal movement. And I agree (except under load - which we both agreed to) But it should not move beyond those norms and should be a part of the power, movement, and transition of energy from the hips. Very rarely are we in a situation where the spine should "create" movement independent from the hips.
Maintaining "long spine" (it really isn't any more complicated than it sounds - pretend there is a string through your spine out the top of your head and someone is trying to pick you up by the string) is a key we both felt was very important to core activation and function.
So we ended up being far closer and agreeing on this but if you look at the internet conversation it appears different.
