Next Friday my school is holding its annual yearbook presentation, and all of us on the yearbook staff (myself included) have to dress up really nice since we're the ones hosting the presentation for the whole school. I'm looking for cute casual dresses to wear but my biggest problem is that my arms aren't exactly shapely and thin....I'm not fat or anything, but my arms are rather flabby. Now I'm not naive, I know I can't expect to have stick-thin arms by the end of next week, but what are some good exercises for my arms to at least shape them up a bit so that they don't look homely with a spaghetti strap dress? =)
