As a woman with curves, Brooks stresses the importance of loving your body and having self-confidence, no matter your size. Accompanying her gym selfie, Brooks writes, "Today my inner being told me to turn up the notch on my self-love. I should not be ashamed of my body. I'm not a walking imperfection! I'm a Goddess. Secondly, I'm a confident woman!"
"Now that I am blessed to be that reflection I was once looking for, I'm making a promise to speak out for that little girl that I used to be."
