There are two types of people during snow days: Those who turn their hygge levels up a notch (or 10) and don’t *ever* emerge from a blanket burrito, and those who brave the elements, clad in a sports bra and leggings, for a quick workout. Yep, I’m talking about you, Karlie Kloss.

During New York City’s recent bomb cyclone, The DogPound (the supermodel’s go-to gym) captured her showing off some skaters in the middle of a snowy street. And considering this exercise majorly heats up the hips, glutes, and inner thighs, the cold weather really didn’t stand a chance of freezing out her sweat-sesh determination.

According to Emily Samuel, a DogPound trainer, lateral movements, such as Kloss’ skaters, are integral to every. single. workout. “People don’t do as many lateral movements as they should, and your muscles are three-dimensional, so you want to work them from all angles,” Samuel told Self.

These types of moves, Samuel added, are extra necessary for workout warriors who primarily move from front to back rather than side to side, as the exercises prevent muscle imbalances and also build up your coordination. And though Kloss used a slideboard to make her snowy sesh of skaters extra fun, you can totally copy the move at home without any equipment. And to start, personal trainer Natalie Johnson recommends going slow with basic form.

“Stand with your feet shoulder-width apart, toes forward. Take a big step to the side with your right foot. Keeping your left leg straight, bend your right knee and hinge forward slightly at the hips, pushing your butt back into a lunge,” Johnson told Self. “Push through your right heel to stand up straight and bring your right leg to center, keeping your knee in front of your body so that you’re balancing on your left leg. Hold here for just a few seconds before stepping back out into another lunge. Do 10 lunges on your right leg, [then] do 10 lunges on your left leg.”

Have the basics down? Now comes the fun part: Start experimenting with lateral hops and speed skaters, and soon enough, you’ll be giving Kloss a run (or slide) for her money.
