I have a great core ;)

Look at me (the picture is from 2002) do you see how nice core i have ???? it looks strong dosent it ?
And NOOO but a have nice abs but thats NOT the core.
I was out walking today and started to think about how people train there so called core and what they think is the core (PT and trainers alike). You have to do lots of crunches, sit ups and Pilates balls to get a good core. But thats not true.
The core is a whole lot of muscles in you body working together as one when you are moving, right muscles should work in right time and right muscles, do you train that by doing crunches ? nope, can you see if you have a nice core by looking at it No.
So way do most of the PT:s and trainers say that?
I dont know, do you?

My daily practice was this today.
Wall squats 10
ASLR Corrective exercise
Shoulder Corrective exercise
Then it was time to practice C&P
16kg 1/1
20kg 1/1
24kg 1/1
28kg 4 ladders of 1-3

Then i went out and took a long walk by the beach and in the forest, it took me a good hour .
Nice relaxing walk
