Working out is so much better in your underwear.

If modeling were an olympic sport, it might look something like the CR Girls 2018 Calendar.

Created by the CR Fashion Book in collaboration with TECHNOGYM, the calendar sees Gigi Hadid, Joan Smalls, Hailey Clauson, Paris Jackson, Hannah FergusonCandice Swanepoel and more running on treadmills and lifting weights in lingerie.

It’s remarkably similar to the approach of this year’s fitness-inspired LOVE Advent Calendar. The difference is this one lasts year-round.

The talent behind the camera is similarly impressive. The photos were taken by estimable fashion photographer Steven Klein and were styled by CR’s founder Carine Roitfeld.

“It’s about the multiplicity of woman in the year 2018,” Carine said of her first-ever calendar for CR Fashion Book in a statement.
