Superficial exercise goals are fairly few in number.
Lose weight. Gain strength. Add muscle. Improve cardiovascular fitness. Reduce pain.
While I might have left out a few, this is substantially the list.
That short list grows to infinite in length once you have added yourself into the equation. And, the more deeply personal your exercise goals become, almost counterintuitively, the more beyond yourself they go.
They reach towards things like legacy, family and your potential for contribution to your world, and how your most able body might enable you to create, participate and bask in those things.
