When it comes to firsts, Michelle Obama seems to break new ground every day. Of course, being the first black first lady is at the top of the heap. But she’s first in many other “first lady” categories, too.

As the media assesses her husband’s first 100 days in office tomorrow, we look at the mark she has made in her short time in the White House:

Tallest: Mrs. Obama is tall (5-foot-11), but she’s not the tallest first lady in American

 history (though there’s a bit of a debate). She’s just shy of that title with, well, this search offers the answer.

Busiest: There’s no official ruling here, but it’s generally agreed that she’s been the busiest first lady during this introductory 100-day period. She visits all over D.C., talks to military families and schoolkids, and has given numerous speeches to government employees and other groups. (Search for details on her schedule.)

Fittest: She’s definitely the buffest first lady ever. Obama does a tough cross-training routine for 90 minutes at least three times a week. This has led to another first: Her toned arms have been studied, debated and endlessly envied. (Search for Obama’s arm workout.)

Most “covered”: The latest tally shows that from the campaign through today, she has appeared on at least 22 major magazine covers: People, Essence and more. She’s the second first lady to make Vogue’s cover. (Who was the first? Answer.) She is also the first person to share the cover of O with Oprah. (Search for that cover photo.)

Everyday fashionista: Jackie Kennedy brought high fashion to the modern-era White House. Nancy Reagan was known for designer duds. But Michelle Obama champions little-known, young American designers as well as wearing clothes from moderately priced retailers such as J. Crew. (Search for more about her favorite designers.)

First to hug the queen: Lest we forget, she was the first first lady to ever hug the queen of England. Etiquette faux pas? (Search for more on that.)
