As a Les Mills x Reebok ambassador, Nina Dobrev has serious fitness credentials; if you haven't tried the GRIT Cardio workout or dance cardio workouts she filmed with the brand, you're missing out on two seriously effective sweat sessions. So when we heard that she hit the gym with Zac Efron — he of the iconically chiseled six-pack — we knew things were bound to be intense. Zac filmed the whole thing for his new YouTube channel, which: 1) thank you; 2) Zac Efron has a YouTube channel now?!; and 3) yes, and I hit subscribe so incredibly fast.
First of all, their friendship is adorable. Nina cartwheeled into the video, they hugged, they chatted about her South African safari while doing planks, they pushed each other on a sled. Nina went into a cryo chamber for three minutes and Zac distracted her from the freezing cold with a bunch of random questions. And I mean the seriously juicy stuff, like: "If you were a vegetable, what vegetable would you be?" (Answer: A carrot.)
"A big part of working out is the community of it and going to workouts with friends, and having that accountability," Nina said in the video. It's a testament to the power of a good workout buddy that they're both still laughing through the whole workout, because, damn, it looks insane.
Watch the full video below to see demos of each move, enjoy their cute friendship, and come to terms with the fact that Zac is still blond. Then, click through the slides to get the details of their go-to moves to incorporate into your next workout.
