heh, i was just joking. Just whenever i hear some sports star or anyone else really, quantify (rather precisely) the amount of effort they're putting in, i wonder how they actually do it? (cause it's a little absurd to think, ok i am doing 80% etc of my capacity)

Also, how do they quantify it? in terms of heart rate, energy spent etc, how can you objectivley measure it so precisely?

I just like the subjective descriptive efforts instead.

eg -> 100% is balls out hard as you can possibly push yourself

That's better

Sorry to get so pedantic, it's part of the humour or lack thereof

Also, i recommend music whilst working out as it helps trigger your flight/fight response! well for me anyway
I actually measured that i can do just that little bit more whilst listening to music. So put your favourite tunes on and plug away!
