If Nina Dobrev has 25 minutes between takes to squeeze in a workout, you’d better believe she’s throwing herself a dance party.

“I dance a lot,” she tells me at an event in NYC last week. “To me, it’s the most fun, because you’re burning a lot of calories and you’re moving, but you’re almost tricking yourself. You end up working out every single muscle in your body, but it doesn’t feel like you’re working out. I like doing things that are fun—I don’t want it to feel like a chore.”

For Dobrev, not only is the actual movement part of a DIY dance party appealing, but it’s also a great way to turn a sweat sesh into a double-duty excuse to hang out with friends and do something they all love. “I’ll plan a workout every day with somebody different and end up having fun and talking and catching up with people,” she says. “Time flies when you’re with friends, you don’t feel like you’re working out. You feel like you’re having fun and living life.”

As part of her latest partnership with Reebok and Les Mills, Dobrev worked with Les Mills to come up with “BODYJAM,” a free, 40-minute dance-based workout that you can do anywhere—whether you’re hanging out at home or in a Hollywood trailer like she is. “It’s high-intensity, a lot of sweat, a lot of fun—the songs are catchy and cool,” she says. “We really tried to break down every move so that a dancer or non-dancer of any level can learn it and feel good about it with their friends and on their own.”

In addition to the high-energy playlist that’s included in her BODYJAM workout, Nina shared 25 minutes worth of music that help her stay hyped up on days when she just doesn’t feel like hitting the gym (or the dance floor). And one more thing that keeps the former Vampire Diaries star motivated? Immortality. “I have a theory that I’m testing out: Hopefully if I just keep up at the level I am, I’ll never die—I’ll become a real vampire,” she jokes. “And that will be because of my workouts.”

Nina Dobrev isn’t the only celeb who swears by DIY dance workouts: Julianne Hough, Jenna Dewan and Jennifer Garner are all also fans. Now, how do we get invited to their next party?!
