Whether you wear your gym clothes to actually work out or they are more like comfy loungewear, they shouldn't end up on a hanger. Sports bras, yoga pants, tank tops, and even lightweight sweaters will last longer when folded. Since they are typically made of spandex and other stretchy material, these pieces easily get warped and misshaped when hung up. Marie Kondo, an expert organizer and author of "The Life-Changing Magic of Tidying Up," has a signature method coined the KonMari fold that will work on your activewear.

If your closet and dressers have reached capacity, you might want to do a wardrobe purge before you fold and store everything. Tidying guru Kondo says to ask yourself, "Does this spark joy?" Take heed to your reaction. If you answer "no," don't bother folding those stretched-out leggings or decade-old bra. Instead, make room for the things that do spark joy. And when you do, make sure to fold them so you can cherish your items for as long as possible.
