Working out with your best girlfriends makes the sit-ups, the burpees, and the planks a whole lot easier to endure. Take it from good pals Isabelle Daza and Solenn Heussaff who go to the gym or, as they dub it, the house of pain, together. Of course, dressed in the coolest sportswear from head to toe doesn't hurt either!

Check out our favorites in the gallery below!
