You don’t want to end up with a plan you anticipate with the same intensity as a barefoot Riverdance class on a floor of misplaced Legos.
Use your interests and personality as your guide. Start by listing the activities you enjoy. Make those the bulk of your plan.
Then sprinkle in the stuff you might not enjoy a whole lot, but know that you need to do to reach your goals.
Sure, you might not end up with the most optimal plan. But there’s no point in having an optimal plan you resent more than a politician resents a term limit. It won’t hold.
The more you can match this whole fitness thing with your interests and personality, the more likely you’ll stick with it. And the more likely you’ll make a habit out of it.
And for now, that’s all that matters. Optimal or not.
