Ashley Olsen's New Year's resolution must be to start exercising ... and dressing more like her ragamuffin sister,
Mary-Kate.

Wearing the latest hipster aerobic ensemble of industrial strength leggings, vintage grunge-era flannel and 2005 oversized shades, Ash pounded the pavement -- sans venti coffee drink -- in L.A. on Monday.
No word on what her goal weight is.
Sportin' a Nick Nolte mug shot weave, '70s nana shades, rosaries leftover from Madonna's 1985 Virgin tour, a scarf made out of the throw from "Roseanne's" couch, a handbag created by an arts and crafts class at day camp and her signature ginormous coffee drink,
Mary-Kate Olsen emerged mostly upright in NYC on Monday.

If you put on that many heinous accouterments, you'd need 20 ounces of caffeine to lift
your feeble bones too.

Defying the Olsen Twin Vacant Stare Code of Stoic Conduct,
Ashley Olsen actually showed some human-like behavior and hugged boyfriend
Justin Bartha after arriving to LAX last night.

No doubt
Mary-Kate will have no feeling either way about this.
Looking like the illegitimate love child of
Nick Nolte's mugshot and
Ozzy Osbourne,
Mary-Kate Olsen threw on a medical smock and went for an unsupervised ride through the East Village this weekend.
She only weighs 48 pounds, so it wouldn't take much for the highly flammable
Mary-Kate Olsen to go up in smoke. Hence a bad idea to pump gas with a cell phone in hand.
Looking like the illegitimate love child of Ozzy Osbourne and Courtney Love, a blood-less
Mary-Kate Olsen made her way to an opera gala in NYC on Sunday.

Rumors that the 22-year-old wonder twin later bit the head off of a bat and blogged incoherently are not true.
After watching that famous
Carol Burnett "Gone with the Wind" skit one too many times, both Victoria Beckham and Mary-Kate Olsen left their houses this weekend sporting some serious drapery hardware.

But unlike Burnett, we're laughing at them ... not with them.
Carrying her trademark 2005 oversized nana shades and a coffee cup, Mary-Kate Olsen maneuvered a NYC sidewalk wearing her finest Chewbacca pelt on Thursday.

MKO is in the running for the title of
PETA's Worst-Dressed Celeb of 2009. With her denim cutoffs and Lindsay leggings, she should have this contest in the (leather) bag!

With a tropical Zorro hat, beachy blue velvet Stevie Nicks blazer, spring shade of black useless scarf, raggedy bell bottoms and Summer of Love platform wedges, Mary-Kate Olsen endured a bitter cold 75 degree winter day in Miami Beach on Wednesday.

No word if she went for a swim in a lambswool bikini or thermal one-piece.
There's been speculation Mary-Kate Olsen has had issues with food. If true, today's car accident won't help much. The driver of the car in which M-K was riding backed into an an El Pollo Loco delivery vehicle in West Hollywood.

Poor Mary-Kate wasn't even there to eat ... she was furniture shopping.
Hopefully she won't have a Pavlovian response to food and bad things happening.
Mary-Kate Olsen tripled her daily caloric intake by enjoying a beer last night in NYC.

That will probably go straight to her ... oh, who are we kidding?
