If you're keeping your ratty old sports bra from high school because you might need it someday, it's probably time to throw it away or donate it. Because chances are, you won't need that sports bra later, and every time you put it on it's dragging you down.
In The Life-Changing Magic of Tidying Up, Kondo writes, "although intuitively we know that an object has no attraction for us, our reason raises all kind of arguments for not discarding it, such as, 'I might need it later' or 'it's a waste to get rid of it.' These thoughts spin round and round in our minds, making it impossible to let go.'"
Sure, you might find yourself in a sticky situation once in a while on laundry day if you only own activewear that you love. But won't you be more likely to actually go to yoga or the gym if you're always wearing an outfit that you feel good in?
If you're still not convinced, consider this: A 2012 study found that we assign symbolic meaning to our clothing. So if we invest in our activewear and love it enough that we'll wear it to other events—brunch, or even happy hour—we're probably more likely to exercise.
"I think it would make sense that when you wear athletic clothing, you become more active and more likely to go to the gym and work out," researcher Hajo Adam told the Atlantic.
Take a deep breath, let go of the things you don't love, and restart your fitness journey. You've got this.
