I let them know my closest experience was working in the backroom in retail and I was willing to learn. Although, the manager literally told me to my face that I looked "too thin" for the position. At the moment I didn't realize how unprofessional that was. In the description it does say you should be able to lift 50 lbs, and I can lift way over that if needed to be. I understand if it was a moving company, but lifting medium sized box is doable for most adults, including myself.
