A low-impact fitness trend that offers a unique rhythm? The 6-6-6 walking challenge introduces a 60-minute daily walk set between a 6-minute warm-up and cool-down. This article puts it through its paces, assessing its appeal, claims, and limitations.
It may sound something of the occult, but at its core the 6-6-6 walking challenge is simply a memorable way to build a framework of fitness with the purported benefits of improved heart health, stress reduction and better sleep.
It consists of a 60-minute walk, either at 6 AM or 6 PM, with a 6-minute warm up and cool down. As a transient ‘challenge’, people usually do it for 7 days at a time. Another variation stipulates two 60-minute walks, one at 6 AM and another at 6 PM.
6-6-6 runs parallel to the "12-3-30" treadmill workout, popularised by social media influencer Lauren Giraldo walking on a treadmill with a 12% incline at 3 mph for 30 minutes.
The main differences? There are no treadmills required with 6-6-6, and you're encouraged to walk 60 minutes instead of just 30.
There is a great deal of flexibility permitted, including options such as indoor tracks or open air walks and hikes. It’s also said that speed isn’t that important. The concept is more so about training yourself to stick with it, as consistent commitment seems to be the only constant in the challenge.
Improved heart health, stress reduction and better sleep are among those listed as possible benefits. The challenge is also highly regarded for fuelling metabolism, allowing for fresh air and setting a positive mental tone for the rest of the day. Research backs these claims, as it was found that 30 minutes of walking reduces the risk of heart disease by 30%.
Likewise, the European Society of Cardiology found morning physical activity to lower stroke risk.
Meanwhile, 6 PM walks play a role in de-stressing and unwinding, easing your body into sleep. They provide a bit of time and space for thinking about what happened during the day and processing thoughts.
If your day is just too full, even a short brisk walk, like 10-15 minutes on your work break is going to make all the difference. The topic of micro breaks is covered in more detail in MOVE Your Way To Metabolic Health.
It is said to burn fat, boost metabolism and promote cardiovascular health, giving your body sufficient time to reach the fat-burning zone, whilst reducing anxiety and tension.
If you can't fit in 60 minutes twice a day, experts recommend at least attempting 10,000 to 12,500 steps daily.
Warming up increases blood flow and the subsequent temperature decreases the viscous resistance of muscle and joints.
The cool-down then aids in recovery by removing waste products from muscles, while increasing flexibility and allowing the heart rate to return to normal.
6 minutes is said to be ample time to initiate their benefits, without eating into your day.
Preventing injury is the main purpose of these warm up and cool down sessions. They can also prepare the mind for the activity ahead, rather than jumping straight into it.
The 6 AM or 6 PM timing may have some scientific basis. Cortisol levels naturally peak in the early morning, while evening walks offer a boost in digestion and amino acid absorption from your main meal.
Morning exercise in particular has been found to be the most beneficial for cardiovascular health.
Weight management is perhaps a controversial argument put forward by fans of 6-6-6. The week-long version of the trend may be flawed in its promises of fat loss, as significant changes in body fat would likely take longer than a week to notice. It’s because, while initial weight loss in a week can be traceable, it's likely to be primarily a loss in water weight (not fat) due to glycogen depletion.
Moreover, noticeable muscle building and strength improvement can take up to 4 months.
While initial gains can be observed within weeks, achieving substantial muscle hypertrophy requires prolonged, consistent training coupled with appropriate nutritional support.
That said, a 2023 article points to walking as a simple yet effective way to support healthier ageing, with links to improved aerobic fitness and modest drops in weight, BMI and body fat. So, in the long term (meaning longer than a week) walking the 6-6-6 way offers plenty of benefits for body composition.
If you look at the 12-3-30 trend and the specified incline of 12%, it may help preserve muscle and support hormone regulation in a way that cardio doesn’t. But, if you're not using a treadmill and are instead walking outdoors, the natural path you take will dictate the intensity of the exercise.
A gradient while walking may be preferable as there is also evidence that combining cardio and muscle strengthening (through use of an incline) helps improve cardiovascular function, enhance lipid profiles and boost cardiorespiratory fitness.
To summarise, while walking to the point of exertion can be beneficial, it’s best to pair it with other exercises like yoga or pilates in your routine for added benefits such as improved flexibility and coordination.
As consistency is key with the 6-6-6 challenge, here are some tips to make it stick:
Walk to something enjoyable like a specific podcast, breathing technique or audiobook.
If you’re feeling like a challenge, use Bala Bangles or Bala Bars to add a bit of extra resistance. A review in the British Journal of Sports Medicine found that 30 to 60 minutes per week of muscle-strengthening activity is linked to a reduced risk of all-cause mortality, cardiovascular disease and cancer.
A walk after work creates a mental boundary between work and home life, especially if you lack a commute to help you switch off.
If you feel brighter after a walk, it’s not a placebo. It’s your nervous system calming down.
Daily movement such as walking also eases screen fatigue by replacing excessive scrolling, encourages better posture, and supports healthy digestion and better sleep.
Walking gives you a chance to unwind and focus on your thoughts, perhaps to find an equilibrium or a more positive outlook on any challenges you may be facing.
It’s been proven that brain health, including hippocampal volume and cognitive clarity, can also be improved with consistent routines like 6-6-6.
Stanford researchers discovered that walking enhances creative thinking. They compared the creativity of individuals while walking to when they were seated, finding that creative output increased by an average of 60% during walking.
Like most wellbeing trends hot off the press of TikTok and Instagram, it’s not a cure all.
But 6-6-6 is definitely a good way to welcome movement into your life. And this force can be used to drive feelings of energy and motivation throughout your day.
It also doesn't demand too much in terms of equipment or environment. Most working people will probably be able to stick to 6-6-6 without excessive burnout and it has some parallels in terms of mindful movement practices like Pilates and walking meditation.
It’s worth reaffirming here that it’s the emphasis on its frequency that counts for 6-6-6, not 10/10 perfect performance. Life gets in the way so you also don’t always have to walk the full 60 minutes. Even 30 minutes has plenty to offer in terms of health benefits.
6-6-6 presents a great way to pair movement with mood management, being more flexible, friendlier and far more forgiving than most other trends that currently circulate in the fitness sphere. Sometimes the most effective solutions come from stripping away complexity.
It’s manageable and realistic, and due to the catchiness of the 6-6-6 number, memorable.
