The treadmill– or as lots of people call it, the dreadmill– does not generally get a lot of love. Now and then, a viral trend will come along and make this piece of physical fitness devices more popular.
One viral pattern called the “12-3-30″ exercise did simply that and is soothingly straightforward: You set your treadmill to a slope of 12 and a speed of 3 miles per hour and after that walk for 30 minutes.
The concept stemmed from social media influencer Lauren Giraldo, who shared it on YouTube in 2019 and once again on TikTok in November 2020, where a video describing the workout acquired almost 12 million views and more than 2.7 million likes (and counting).
” I used to be so frightened by the fitness center and it wasn’t encouraging,” Giraldo explained in the 37-second TikTok video. “But now I go, I do this one thing, and I can feel great about myself.” The 12-3-30 exercise, Giraldo stated, helped her lose 30 pounds.
When it comes to the origin of this routine? “I’m not a runner, and operating on the treadmill was not working for me,” Giraldo informed TODAY.com. “I started playing around with the settings, and at the time, my fitness center’s treadmill had 12 slope as limit. The three miles per hour felt right, like strolling, and my granny had actually always told me that 30 minutes of workout a day was all you required. That’s how the mix began.”
Giraldo isn’t the only one who swears by this routine. Search “12-3-30 exercise” on YouTube, and you’ll see lots of rave evaluations praising it as a fantastic method to slim down, increase physical fitness, and feel thrilled about exercise. Is 12-3-30 truly worth the hype? We asked three physical fitness specialists to weigh in.
Is 12-3-30 a Good Workout?
The 12-3-30 exercise centers on strolling, and walking, in basic, is a terrific type of lower-impact workout, stated exercise physiologist Janet Hamilton, CSCS and running coach with Running Strong in Atlanta.
Routinely strolling at a brisk speed offers a ton of health benefits, consisting of strengthening your bones and muscles, improving your balance and coordination, and preventing or handling conditions like heart disease, high blood pressure, and type 2 diabetes.1.
For most people, strolling is typically a moderate activity, Hamilton said. However walking quickly at a steep slope– which is what the 12-3-30 workout entails– will probably feel more like a vigorous activity for many folks.
” You have to be in pretty good shape to address that rate which incline for 30 minutes,” workout physiologist DeAnne Davis Brooks, EdD, associate teacher in the department of kinesiology at the University of North Carolina Greensboro and USATF Level 1-track coach, told Health.
That’s because when you walk at an incline compared to flat ground, there’s more gravity resistance trying to pull you back down, and your muscles– particularly the muscles in your butt and the backs of your legs– have to work additional tough to overcome that included force. As an outcome, your heart will instantly work harder, making the activity a cardio difficulty, too.
A 2 to 7 percent slope increased heart rate by almost 10 percent when compared with running on a flat surface.2.
By that measure, the 12-3-30 can be an excellent way to ramp up the strength of routine ol’ walking, Brooks stated. It may be a strong pick for individuals who can’t do high-impact activities like running, however still want a more energetic routine, Brooks included. The 12-3-30 is really simple. You can simply hop on the treadmill, set it to the proper slope and speed, and then you’re great to go.
Another plus of the exercise: If you do it 5 times a week, which is the frequency Giraldo does (according to her TikTok video), you’ll satisfy the recommendations set out in the U.S. Department of Health and Human Services Physical Activity Guidelines, Brooks said.3 These guidelines urge adults to get at least 150 minutes of moderate-intensity activity a week, or at least 75 minutes of vigorous-intensity activity a week.
Now, about those weight-loss claims: Weight loss is a little bit more complex than simply a single exercise. If your objective is to slim down, you need to burn more calories than you consume, and a healthy weight loss program will preferably integrate exercise with diet modification, Selina Shah, MD, board-certified sports medicine and internal medicine private practice doctor with Bass Medical Group in Walnut Creek, California, told Health.
Because case, the 12-3-30 exercise might be part of a healthy weight reduction program, but Dr. Shah pointed out that any type of exercise can meet that function. Scientific research from 2020 shows that exercising around 300 minutes a week can cause weight loss and a reduction in body fat.4 The 12-3-30 exercise, regrettably, doesn’t rather satisfy that standard– even if you do it every day (which the experts do not recommend; more on that in a minute).
Exist Any Risks or Drawbacks of the 12-3-30 Workout?
The 12-3-30 exercise provides some benefits, however is it a miracle workout? No, Brooks said. There are lots of other workouts you can do that will deliver a comparable metabolic need, Hamilton stated, consisting of cycling at a moderate effort, playing a video game of singles tennis, or swimming at a moderate speed.
Plus, the 12-3-30 is not without risks. “Any time you stroll up that steep of a grade, that’s a lot of load on your lower back,” Hamilton said. The exercise likewise requires a lot of your hamstrings and calves, Hamilton included, so you might potentially strain these muscles if you delve into the routine without properly preparing your body.
People with knee problems would likely struggle with the 12 percent grade, Dr. Shah stated. And if you don’t have strong enough muscles in your hips, thighs, and core, you might intensify underlying problems in your knees or ankles, or increase your risk of injuring these joints, Dr. Shah added.
There’s likewise the simple fact that walking inside on a treadmill set at a fixed incline does not provide the very same advantages as strolling outdoors on varying terrain. Strolling on irregular ground– say, a path with rocks and roots– will challenge your balance and work the muscles in your lower legs more than if you were walking on the predictable surface of a treadmill, Hamilton said.
Furthermore, strolling outside supplies dosages of fresh air, sunlight, and altering scenery– advantages you definitely won’t get on the treadmill.
Finally, though the 12-3-30 can be part of an exercise routine, Dr. Shah stated, but it’s not recommended as your only kind of workout. “It’s crucial to develop and use different muscle groups,” Dr. Shah stated, as that will minimize your threat of overuse injury and enhance your general fitness. Mixing up your physical fitness routine will also help you keep inspiration and reduce boredom, Brooks said.

When you’re ready to attempt the 12-3-30, take notice of your kind. Stroll with your arms swinging opposite your legs, and do your best to keep your hands off the rails or the front screen of the treadmill, Brooks stated. (If you’re struggling to balance, you can hover your arms over the rails or gently rest your fingertips on top, Brooks stated– simply do not support your body weight on the rails.).
” The more you can mimic actually strolling by yourself power, the greater the fitness advantages will be,” Brooks discussed. “Your heart rate boosts, the intensity increases, you’re burning more calories that method.”.
