Nothing will motivate you to workout more than a new outfit. I highly recommend buying a few, new workout outfits before you start because you will want to wear them and they may get you to work out. As you reach different goals, you can buy yourself a new tank or leggings as a reward. Much better than a food reward. I have never been and will never be a size 2 so I have a very strong opinion of workout clothes companies.
My favorite, hands down, is Athlete. Great selection, big size range, great quality, pretty reasonably priced, cute/fun clothes. They are owned by the same company as Old Navy and Gap. I have an Old Navy card and can earn rewards for shopping at any of those companies plus Banana Republic and Sierra Trading Post online. You can earn $5 and $10 rewards that can also be used at any of those companies. They also often have additional %s off, sales, clearance…online store is great. Free shipping (I think) when you spend $50.
I also like TJ Maxx/Marshalls. Inexpensive, cute workout clothes. Not as big of a size range and quality is not as good. They also have workout accessories: yoga mats, weights, water bottles, headbands, etc. If you have a TJX card, you can also earn rewards.
As I’ve said before, I am NOT paid by any of these companies. They are just my personal favorites. I hope this was helpful to you. Have a fashionable day!!
