The holidays can be a crazy-hectic time. With so many items on your to-do list, it’s hard to know where to start. And one thing that often falls by the wayside: your workout. Which is why we tapped Astrid Swan—the trainer behind Hollywood A-listers like Shay Mitchell, Olivia Munn and Julianne Hough—for a no-fuss routine (you only need a towel!) that will crush major calories, tone you all over, and pump that heart rate all the way up, all while your holiday dinner is cooking.

“This workout plan is so simple because you don’t need to go to the gym, so there are no excuses,” explains Swan who wants to stress how fun it can be trying to sneak this fat-burning circuit in between mashing potatoes, cooking the turkey, or prepping whatever else you have on the menu. “Plus, you’ll feel better after you get in a little sweat, and it’s not going to make you drenched, so you won’t ruin that blowout either.” Talk about a win-win!

Do each exercise for 50 seconds, followed by a quickie 10-second rest; complete 4 rounds. And then admire how good your body—and that seven-course meal on your table—looks!
