What is the viral 6-6-6 walking challenge, and what is this weight-loss trend really doing to you?

If you’ve been anywhere near TikTok or Instagram lately, chances are you’ve come across a curious fitness routine dubbed the “6-6-6 walking challenge.” No, it’s not what it sounds like—it’s not satanic, and it’s not a gym cult either. In fact, this viral challenge is surprisingly wholesome, aiming to improve physical and mental health by encouraging a structured walking habit. But does it live up to the hype?

According to a report in Women’s Health, the 6-6-6 challenge involves walking for 60 minutes a day at either 6 a.m. or 6 p.m., beginning with a six-minute warm-up and ending with a six-minute cool-down. It’s the latest in a long line of numerical fitness trends—think 12-3-30 or 3-2-8—that simplify workouts into digestible routines.

Why the Hype? The Psychology of Simplicity

Part of the appeal lies in the ease of remembering the format. Lindsey Bomgren, CPT and founder of Nourish Move Love, told Women’s Health that people naturally gravitate toward number-based challenges because they remove guesswork and offer a clear, repeatable formula. “It’s accessible to all fitness levels while still offering tangible health benefits,” she noted.

Plus, the challenge encourages consistency—often the missing ingredient in long-term fitness success.

Walking the Talk: What Science Says

While it may seem too simple to be effective, walking has long been backed by research as a powerful tool for overall health. A 2021 JAMA Network Open study found that adults who took at least 7,000 steps a day had up to a 70% lower risk of mortality than those who didn’t. Since the 6-6-6 method encourages about an hour of walking (roughly 6,000 to 7,000 steps), it could have meaningful health implications if sustained.

As for the specific timing—6 a.m. or 6 p.m.—Bomgren points out it’s more about habit-building than magic hours. However, walking post-meal has been shown to regulate blood sugar, aid digestion, and boost heart health.

Weight Loss and Beyond

If weight loss is your goal, this trend could help, but it’s not a silver bullet. Janet Hamilton, CSCS and owner of Running Strong, notes that while any additional movement can aid in weight loss, it must be paired with dietary adjustments to create a calorie deficit. “You might see your weight drop gradually over time, but it's not just about the steps,” she says.

A 2023 Obesity study even observed that people who worked out early in the day had lower BMIs and smaller waistlines—though it stopped short of proving direct causation.

A Holistic Wellness Boost

Beyond shedding pounds, walking strengthens bones, supports cardiovascular health, and enhances mental well-being. A PLOS One study from 2022 linked brisk walking to improved bone density, while a JAMA study tied higher step counts to reduced mortality.

The mental health benefits are equally compelling. A 2024 review in JAMA Network Open found that walking reduced symptoms of depression, and a 2022 analysis in Applied Psychology revealed walking in nature significantly eased anxiety.

Though six-minute warm-ups and cool-downs may seem arbitrary, they’re right in line with recommendations from the American Heart Association. They help prepare your body for exertion and ease it back into rest, reducing injury risk and aiding recovery.

In a sea of fleeting fitness trends, the 6-6-6 walking challenge may actually have staying power. It isn’t a magic bullet, but it might be the nudge you need to get moving. Whether you’re chasing a healthier heart, a trimmer waistline, or simply a bit of mental clarity—walking just might walk you there.
