Understanding what they are is bliss. Who would be seduced by mara to think that fitness is of great importance? The only thing of importance is the development of panna, which leads all ten perfections.
Besides, even if one does want to be healthy it is fine, but one must understand these dhammas for what they are and reflect on them as one does things such as work out or swim. Naturally panna can develop. It can also be said that a healthy body arises because of certain conditions. Through the practice of ten perfections, which become natural when panna is developed, one accumulates the causes for long life (by refraining from harming other living beings) for wealth (through the practice of generosity) and so on.
You are aware the Buddha walked in meditation for physical exercise?
The heart of the path is SO simple. No need for long explanations. Give up clinging to love and hate, just rest with things as they are. That is all I do in my own practice. Do not try to become anything. Do not make yourself into anything. Do not be a meditator. Do not become enlightened. When you sit, let it be. When you walk, let it be. Grasp at nothing. Resist nothing. Of course, there are dozens of meditation techniques to develop samadhi and many kinds of vipassana. But it all comes back to this - just let it all be. Step over here where it is cool, out of the battle. - Ajahn Chah
