Buying cute workout clothes is totally worth it! It makes me want to go to the gym more, always good. I get mine mostly at the outlets! Nike, Adidas, and Under Armor, you can get pretty good deals. Also, Old Navy has super cheap, pretty cute ones too! Honestly, I have legit two gym outfits, recently up from one, and I just wear the same thing every time so I never have to think about it. Also, Lululemon is straight up the devil. Never go there.
