Rachael Burks and Julian Carr have their mean faces on. They're grunting, gasping, making expressions that are usually unwanted when taking ski photos. In this case, they can’t help it.

 Burks and Carr are at Boxing is For Girls, a Salt Lake City gym geared toward beating the snot out of people—and not just ladies—in the name of fitness. They’re going through trainer Eliza James’ specially designed Chance workout, an ass-kicker that combines strength, endurance, and pushing your pain threshold. Ironmen and marathoners can’t even get through it, not even close. But Burks and Carr are definitely trying—and as some of the most badass skiers out there, they are doing a solid job.

 “Work hard for your break, come on!” James yells. “You want all your hard work to pay off.”
