Jennifer Garner knows what it takes to fuel a superhero.

The actress, 52, who played Elektra for the first time in 19 years in Deadpool & Wolverine, is sharing her secrets to how superheroes stay in shape!

“Elektra Smoothie. A great and filling way for all superheroes – cape wearing or not – to start their day. ,” Garner captioned an Aug. 6 Instagram video, which was part of her Pretend Cooking Show series.

In the clip, the Marvel star was dressed in character in what appeared to be a man-made cave on set as she mixed a perfect blend of nutrients starting with protein powder and a handful of spinach.

The ingredients appeared in text on the screen as she continued to mix, but Garner also shared her recipe in the caption: “1 serving protein powder, 1 Tbsp ground flaxseed, 1 Tbsp chia seeds, 1 Tbsp almond butter (if no one’s looking I use extra…), 1 cup almond milk, Handful of fresh spinach, Handful of ice [and a] Small handful of berries (please see almond butter, also true here ).”

She credited clinical nutritionist, celebrity health coach and best-selling author Kelly LeVeque in the caption of the post for helping her with the special mix.

The Daredevil alum showed her process every step of the way, and was sure to warn others before introducing loud sound by yelling, “Blender!”

Once the smoothie was near completion, Garner gave it a final manual mixing using one of her sais (a pointed melee weapon originating from Okinawa that is utilized in Okinawan kobudō, ninjutsu, and southern Chinese martial arts).

She also did a taste test using the sai as a spoon.

“Have a good day,” Garner said at the end of the video.

The day prior, she shared an Aug. 5 Instagram video of herself doing intense workouts in order to step back into the role after a nearly 20 year hiatus.

“Becoming Elektra” was written across the clip, and in the caption, Garner admitted, “I was fit, but not @marvel fit. .”

Her video showed off rigorous training sessions, ending the video with a clip of her in full costume, perfectly twirling her sais before taking a bow.

In Garner’s caption, she said that thanks to “@slevydirect [Shawn Levy] and @vancityreynolds [Ryan Reynolds having] the idea for Elektra Natchios to show up in @deadpoolmovie 3,” that she and her “bestie and OG stunt double” Shauna Duggins “were in heaven on set with them.”

The actress also praised her costars Hugh Jackman, Dafne Keen, Channing Tatum and Wesley Snipes for being a pleasure to work with.

“Shooting the fight was so fun, being there all together—truly like a dream. I’m proud of my friends and grateful to be up there with them. Thank you doesn’t cut it, guys, but it’s a good placeholder until I figure out what does. ♥️,” Garner concluded.

Deadpool & Wolverine is in theaters now.
