Two masses balance gently on a lever
To understand this meaning don't be clever
Perhaps it is the mind that makes us smart
Yet we'd not be alive without the heart
Now swimmers -- they have their one hundred yard base
And for bikers the "zone" is what dictates their pace
But might I suggest a quite different approach
In a sense, you'll consider yourself as your coach
You do not need a plan; you can play it by ear
Without ever forgetting to honor your peer
[And] so long as you train with the best of intentions
You will see results of astounding dimensions
