it was a comedic analogy... In no way am I saying that a old outta shape dude is on par with a professional athlete- I find it distressing that you fail to pick up on that.
So- you are telling me that it doesn't matter how that ToP is spread out? You equate the physical fatigue of 2 min on, 2 mins off, 2 minutes on, 2 minutes off, 2 minutes on, 2 minutes off, 2 minutes on, 2 minutes off, 2 minutes on, 2 minutes off, 2 minutes on, 2 minutes off, 2 minutes on, 2 minutes off, 2 minutes on.
to
14 minutes off, 16 minutes on.
???
Tell you what, go and run a Kilometer in two manners - do 100m sprinting, 100m walking, 100m sprinting, 100m walking, 100m spinting, 100m walking, 100m sprinting, 100m walking, 100m sprinting, 100m walking.
then
go and do 500m walking then sprint the last 500m. let me know which you think has the greater amount of physical exhaustion.
