Round 13: Aurora

Without magic, she's hardly shown any strength or any physical activity except walking up the North Mountain. I'd still say Anna put in more effort with her rowing of boat, hiking up the mountain and then running when Snowman attacked. So slightly more fit than Elsa.

What was said above.

I don't really remember any scenes of her in her movie involving any sort of physical activity - except running around in the creepy forest.

^scrubbing an entire palace takes somewhat of physical stamina. She worked tirelessly in the palace as well as cottage. Cooking for 7 people also takes stamina if not strength. I'm not saying she's the strongest, though.

I also agree with anukriti2409. The other girls who were inside were cleaning, which is somewhat exercise, and doing more physical activities than Elsa seemed to be doing. Without powers Elsa comes off a bit frail for such a young woman.
