I am sorry that is gay.'Functional' is relative. That has no relevance in the real world at all.
Hahahaha....that dude's gonna look like a fool when "life" tests his level of functional strength and he has to move two shipping ropes in various wave-like patterns for a long period of time or else die!
FUNCTIONAL and CORE are two of the stupidest, most over used terms that I've heard in the last few years. Train EVERY muscle group with moderate to heavy weights and your CORE will be strong. Your overall muscular strength will also improve, so they will be functional.
I love those words because it helps to spot idiots easily. any ''expert'' that use the word 'core' or 'functional', are fucking idiots. every muscle is functional and core=abs+lower back. whats up
u should start a training thread on the training board to help ustalk to chaos hes a mod on that board
