There are a few products that I can't live without, and those things include:
-A sturdy sports bra
-Water bottle
-Egg whites/ whole eggs
I used to be obsessed with my weight-lifting belt, but since I no longer competitively powerlift, that belt hasn't really been used. One thing I REALLY miss are my squat shoes. Since I do squat high-bar, my heels naturally raise up. I have been using plates under my heel, but I'd totally re-buy squat shoes.
