FRC= Functional Residual Capacity, is the volume of air in your lungs after a normal, not forceful, exhale.
I have found difficult to relax while apnea walking, the max I have done is 1´30", but I have done 2´30" in water.
I only made 1´of apnea walking in FRC

I have also a max of 1´30", and around 50 seconds with FRC. But I have never done apnea walking in water..
So what discipline have you done ´2´30" with??
When i did a 50 meter DNF i used around 1 minute... I think that is the record for me while swimming underwater.:head
