For her #FitnessFriday post this week, she's focusing on all things nutrition-related. "Our inner warrior is only as good as how we choose to nourish it, and what we eat builds our foundation," she captioned an Instagram photo. (Where her back looks insanely toned, btw.)
One topic they covered on their Instagram Stories Q&A: How to fuel a workout. While her trainer Peter Lee Thomas cited foods like eggs, avocado, and nuts as his go-to fitness fuel, Halle could only talk about one thing: Hint Kick caffeinated water.
"What I plan on every day when I work out is this Hint Water with a kick," Halle says in her Instagram Stories video, while holding up a bottle of apple and pear flavoured Hint Kick.
"You need water to stay hydrated, and Hint has caffeine in it, but it's a natural caffeine," she says. "And I drink three to four of these every workout." Yep, three or four.
In her #PhitTalk, Halle also revealed that "I have a soda tooth, I like diet coke sometimes." But she is trying to opt for healthier alternatives whenever she can, like kombucha, Perrier with some fresh lemon, or La Croix.
To avoid eating unhealthy snacks on the reg, Halle says she prefers to keep things like chips, cookies, and other unhealthy snacks out of her house entirely. And when she does buy treats for herself or her kids, "I keep them locked up, so we don’t have access to them," she says. That way, "it's more of a mindful decision to get them out."
And case you're wondering, Hint is a brand of flavoured water that's sweetened with "natural fruit flavours" and "free of calories, carbs, sugar and high fructose corn syrup or diet sweeteners," according to the Hint website. While currently unavailable in Australia, their "Hint Kick" variety also has 60 mg of caffeine. To put that into perspective, that's less than a third of the amount of caffeine in a large cup of coffee.
So, no, you're not going to be bouncing off the walls after three or four of these flavoured drinks. But hey, incorporating caffeine into your sweat sessions - say, with pre-workout or Avitae - may just give you the little extra oomph you need to keep up with badass Halle's. (One can dream!)
