I'm so stressed because whenever I wear a cardigan, my upper arms feel like they stand out even more...

I've been exercising and paying attention to my diet, but my arms just just won't budge. ㅠㅠ

I feel like I've lost some weight overall, but this specific area remains the same, which bothers me even more.

In this case, is continuing to lose weight through exercise the answer, or are there other methods? I'm curious.
