There were so many amazing shots that came out of our photo shoot with February’s cover model, Katelyn Prominski of the Pennsylvania Ballet, that I had to share them with you. If her perfectly toned abs and crazy-flexible limbs don’t inspire you to get your sit-all-day-self to the gym or to recommit to those New Year’s resolutions—they sure motivated a few Philly Mag staffers!—not much else will. Enjoy! Photography by Brett Thomas; Hair and makeup by Liz Jacobs; Styling by Zoey Sless-Kitain; Clothing courtesy of Lululemon.
