The 12-3-30 workout was coined by 24-year-old social media maven and YouTuber Lauren Giraldo. It consists of setting a treadmill to an incline of 12 and walking at 3 miles per hour for 30 minutes. Sounds easy enough. Well, according to hundreds of commenters, it's actually "a lot harder than it seems."
The number of 12 3 30 calories burned during this workout can vary based on factors such as your weight, age, and intensity level. However, on average, a person weighing 150 pounds can expect to burn approximately 300-400 calories during a 30-minute workout.
The 12-3-30 workout for beginners includes modifications that allow you to work up the treadmill workout created by fitness influencer Lauren Giraldo. The original incline treadmill workout is simple: Set your treadmill at 12% incline, at 3 miles per hour (mph), for 30 minutes.
It's something you can do on your own, and you'll probably start to notice a difference in your body and overall relationship with the gym after the first week.
The U.S. Department of Health and Human Services recommends moderate-intensity aerobic exercise for 150 to 300 minutes a week. Doing the 12-3-30 workout five times a week will get you into the low end of that range.
Walking along hills (or on an incline treadmill) can increase cardiovascular health, build muscle, and burn calories. An incline workout makes your body work harder than it does on smooth ground since you're working against gravity and propelling yourself upward.
The Popular 12-3-30 Workout
The 12-3-30 workout is straightforward - set your treadmill to a 12% incline and a speed of 3 mph. Walk for 30 minutes. This workout is easy to remember and can be done by anyone, regardless of their fitness level.
Enter the 12-3-30 method – walking on a treadmill with its incline set to 12, at 3mph, for 30 minutes. Influencer Lauren Giraldo brought the method into the mainstream, claiming it helped her lose 30lb (just over 13.5kg).
The best walking speed for fat loss is usually between 3 to 4 miles per hour. This pace is brisk enough to increase your heart rate and calorie burn, making it effective for fat loss.
It can lead to early fatigue and overexertion, which might discourage continued exercise. It's essential for users to assess their fitness levels and start with a manageable incline. Potential for poor posture: Maintaining proper posture on an incline is more challenging.
Although you cannot specifically target the belly or other fat by walking on a treadmill, performing aerobic exercise such as walking can help you burn away overall body fat. Combined with a healthy diet and strength training, walking on a treadmill for 30 minutes a day can help you reach your fat-loss goals.
HIIT (High-Intensity Interval Training)
HIIT is one of the fastest ways to burn belly fat. It's easy: alternate between short, fast running and longer, slower recovery periods. This burns a lot of calories and keeps your metabolism high even after you're done.
Simply put, incline walking refers to walking uphill at an incline rather than on level ground. While this can be done on an actual hill, incline walking on a treadmill with the grade set to at least 3 percent is a safer option for your joints since you never have to switch directions and walk downhill.
12-3-30 isn't meant to be an everyday exercise. Even though Lauren Giraldo did this workout five days per week to see her results, there are some drawbacks to doing the same workout every day, including injury from repeating the same motion too often and boredom.
Most people burn 30-40 calories per 1,000 steps they walk, meaning they'll burn 300 to 400 calories by walking 10,000 steps, Hirai says. However, this is just an estimate. Each step you take burns calories, but the exact amount is highly individualized. "Calorie burn rate can be quite variable," he says.
Here's an estimate 12-3-30 calorie burn for men across various weight ranges: 150 pounds: Burns approximately 250-300 calories. 175 pounds: Burns approximately 300-350 calories. 200 pounds: Burns approximately 350-400 calories.
The 30-30-30 diet is a popular weight-loss trend that calls for eating 30 grams of protein within 30 minutes of waking up, followed by 30 minutes of low-intensity exercise.
A: While running may burn more calories in a shorter time, increasing the incline and speed of your walking routine can make it more challenging and equally effective for weight loss as compared to running, especially for those who have joint concerns or are unable to run.
For starters, the 12-3-30 treadmill routine is a banger of a lower-body workout, says Gott. "It's a great way to activate multiple muscle groups in your legs." Your quads, hamstrings, glutes, and calves are all firing, which means that over time, it can help you build lower-body strength.
