Making her cameo appearance as the iconic dagger-wielding Elektra took some serious work.

Folks who follow Jennifer Garner on social media are well aware and fond of her often adorable antics, down-to-earth sense of humor and heartfelt kindness. But let’s not forget—she’s also pretty badass.

And nothing proves this quite like a recent video the actress posted to her Instagram showing the incredibly intense workout she endured to get ready for the return of her Elektra persona in “Deadpool and Wolverine.” Seriously, some of these exercises look Olympian level.

When Ryan Reynolds and “Deadpool” director Shawn Levy approached Garner about joining the film, she was, as she put it, “fit but not Marvel fit.” Plus she hadn’t worked with sais—Elektra’s signature weapon—in two decades.

So, to make this “impossible dream a reality,” Garner did weapons training, martial arts drills and two strength workouts a day with her stunt double Shauna Duggins. Which, judging by the clip, consisted of tons of plyometric jumping involving a mini trampoline, boxes, resistance bands, dumbbells, the whole works. There’s even an upper body exercise where she planks on a bosu ball that looks particularly excruciating.

But wait, there’s more! She also committed to boxing three times a week, plus cardio. Lots and lots of cardio. Garner mentioned working with Peloton, and can be seen running and swimming throughout the clip.

Just goes to show how much behind-the scenes work it takes to make something look effortless. And mind you, this was all this for a cameo appearance!

Two other cool things worth noting. One, when Garner says she was already fit, she ain’t lying. Her regular workouts are nothing to sneeze at, and she prioritizes nutrition (remember her viral “big fat daily salad” moment?). This no doubt made the bounce back much easier. And while we might not all be able to do daily salads and intense exercise, there are consistent healthy habits we can all stick to that give us a strong baseline. So the moment we are tasked with becoming superheroes, we’re ready!

Two, even while in great shape, Garner does not ace every move on the first go, especially with those sais. But there is a measurable, noticeable progress that happens. And her having a smile on her face the whole time undoubtedly helps. She even wrote that there was a lot of “laughing at sore bodies.” A good attitude goes a long way, just saying.

In other words, Jennifer Garner really is a superhero—inside and out!
