Astrid McGuire can handle celebrity asses, but she's done with her husband's -- the famed trainer is calling it quits on her marriage.
McGuire filed papers in L.A. last month after ten very healthy -- on her end at least -- years of marriage to husband, Michael Heier McGuire.
Whipping stars like Christina Applegate and Julianne Hough into shape at Barry's Bootcamp has put her in high demand -- and she's modeled since she was 15.
According to the divorce docs ... divvying up of their property will be handled by a written agreement -- so, should be a clean split.
Astrid's clearly taking her best assets with her.
