Have you ever noticed how much a dose of movement impacts your mood?
If you've been sitting down all day and you go outside for a walk, you are likely to feel better. I know I do. However, if you go to a practice session with unreasonably lofty expectations ('I'm gonna do this hard thing I saw and it'll be perfect, just like that Instagram video'), you probably won't leave feeling like a winner. And if you're not skilled at overriding and reframing your own nay-saying... you might not walk away feeling vibrant.
You've likely heard of the research which confirms that exercise is mood boosting (it's usually accompanied by a stock image of people in bright-colors faux-grinning on a jog). While movement does provoke chemical changes that make you feel nice, your approach can amplify the positive after-effects or knock them right out of you.
