What is the 12-3-30 Treadmill Rule? Can it Really Make You Lose Weight?

Here are the answers to your burning questions about the 12-3-30 Treadmill Rule


The 12-3-30 treadmill rule has recently gained popularity as a fitness strategy that promises to help people improve their physical fitness and overall health by losing a considerable amount of weight over a period of time. This rule is a relatively simple concept that involves doing cardio exercise on a treadmill for 30 minutes, at a speed of 3 miles per hour, with a 12% incline. But does this rule really work? In this article, we will explore the 12-3-30 treadmill rule and examine its benefits and potential drawbacks if there are any.

What is the 12-3-30 Treadmill Rule? How did it Originate?

The 12-3-30 treadmill rule was created by fitness influencer and personal trainer Lauren Giraldo. The rule is designed to provide a high-intensity workout that can help individuals burn calories, improve cardiovascular health, and increase muscular endurance. The concept is relatively straightforward: Set the treadmill at a 12% incline, which is the maximum incline for most commercial treadmills. Then, walk for 30 minutes at a speed of 3 miles per hour.

The reason for the specific speed and incline is to achieve an optimal heart rate zone that is suitable for weight loss and cardiovascular health. A 12% incline is a steep enough grade to challenge the body and engage muscles in the legs, buttocks, and core. This challenge is what helps burn more calories during the workout, making it an effective strategy for weight loss.

Walking at 3 miles per hour is also an essential component of this rule. This speed is a moderate-intensity level that elevates the heart rate to an optimal level for burning fat and improving cardiovascular health. Additionally, walking at this speed ensures that individuals can complete the full 30 minutes of exercise without feeling overly exhausted or discouraged.

Benefits of 12-3-30 Treadmill Rule- Find Out if You Can Lose Weight with this Fitness Strategy

One of the most significant benefits is weight loss. This rule provides a challenging and effective workout that can help individuals burn calories and shed pounds. Additionally, the incline engages muscles that are often neglected during regular walking, resulting in toning and strengthening of the lower body.

The rule also improves cardiovascular health. Walking on an incline can increase the heart rate and improve blood flow, leading to better heart health. Regular exercise, such as the 12-3-30 rule, can also reduce the risk of developing chronic diseases such as type 2 diabetes, high blood pressure, and heart disease.

Finally, the rule is a convenient and accessible workout that can be done by anyone, regardless of fitness level. Walking on a treadmill is low-impact, making it an ideal exercise for individuals with joint pain or injuries. The 12-3-30 rule is also customizable, allowing individuals to adjust the speed and incline to their fitness level.
