I was reading about chaos and fractal physiology, and how the variability of the heart rate is a good thing because it helps to prevent fatigue. When I read that I was reminded of a Paul Chek article from t-nation about pattern overload:
I don't think he ever says anything about chaos theory or fractals, but all this really brought to light what he was saying.
Since machines lock you into an exact pattern, they prevent nervous system variability, which is bad like a lack of variability is bad for the heart and brain (lack of variability is what leads to seizures). That is, machines lack the natural chaos that we would find in every repetition done with free weights.
Robb, do you think Bruce J. West would be a good interview for a future PM?
