Round 10: Anna
Round 11: Belle
Round 12: Elsa
Round 13: Aurora

Working two shifts was tough but she worked in a professional environment, which gave her basic facilities. Unlike Snow and Cinderella, where they were made to work like maids and burdened with unreasonable workload.

I bet she's soft all over with a bit of chub. I really don't see how working as a maid makes you more fit when Anna has done some physical stuff.

Either her or Snow.

I agree with anukriti2409 and think it's all close between Snow White, Cinderella and Tiana who would all experience such heavy work loads taking a toll on their physical fitness in some areas and strengthening their fitness in other areas. That being said, I still think Snow White and Cinderella would be in better shape because Tiana seems to not do much beyond cooking and serving, which is far less physically demanding than Snow White and Cinderella's maid responsibilities.

For Snow White (especially) and Cinderella, they were working in a time where cleaning was much tougher and physically exerting as they had to hand-wash all laundry, scrub floors without mops etc. (just a rag with soap and bucket of water) and clean everything without modern technology that changed chores from taking hours and days to just minutes to hours today. Not having any electricity at all also requires working extra hard to get everything done by sundown as well.

Same as before.
