Proponents of the workout claim that this combination of incline, speed, and time creates an optimal environment for burning calories and improving cardiovascular fitness.

- It's essential to note that while the 12-3-30 workout can contribute to weight loss and cardiovascular health, a well-rounded fitness routine should also include strength training and flexibility exercises for overall physical well-being.

- The treadmill routine known as #12-3-30 has surged in popularity among fitness influencers and TikTok enthusiasts, accumulating a staggering 431.1 million views on the platform. But the burning question remains: does this seemingly simple workout actually deliver results?

- The 12-3-30 workout, originating from a YouTube post by influencer Lauren Giraldo in 2019 and later going viral on TikTok in November 2020 as part of the #HotGirlWalk trend, advocates for a straightforward approach. Set the treadmill incline to 12%, pace at three miles per hour, and walk for 30 minutes—a formula that purportedly helped Giraldo shed 30 pounds.

- Giraldo, who confessed that traditional treadmill running wasn't effective for her, explained that the combination of settings felt like brisk walking, aligning with her grandmother's belief that 30 minutes of daily exercise is sufficient.

- Despite its simplicity, the 12-3-30 workout has garnered attention for its low-impact nature, providing a workout without straining muscles or joints. But does it truly deliver tangible benefits?

- Walking, a cornerstone of this routine, has long been celebrated for its myriad health advantages, contributing to both physical and mental well-being. Research published in the Journal of the American Medical Association links brisk walking to a reduced risk of heart disease and dementia, while exceeding 10,000 steps per day may correlate with a lower cancer and mortality risk.

- The 12-3-30 workout's distinctive feature, the 12% incline, intensifies energy expenditure and calorie burn. A study from the National Library of Medicine reveals that walking with a 10% incline increases caloric burn by an impressive 32%, concurrently building muscle in key areas such as glutes, quadriceps, hamstrings, and calves.

- Dr. Robert Glatter, a board-certified emergency medicine physician, underscores the broad benefits of walking at a moderate to vigorous pace, promoting memory, sleep, cognitive function, and weight management. He emphasizes that even a slower to moderate pace for 15 to 30 minutes, three days a week, can yield positive health outcomes.

- However, experts caution against underestimating the intensity of the 12-3-30 workout, urging newcomers to gradually adapt to the incline to prevent strain or injury. Individuals with knee issues are advised to approach this regimen with caution.

- Executing the 12-3-30 routine five times weekly aligns with the U.S. Department of Health and Human Services Physical Activity Guidelines, recommending adults engage in at least 150 minutes of moderate-intensity activity weekly. Yet, the guidelines also stress the importance of incorporating muscle-strengthening activities, such as weightlifting or push-ups, at least two days per week.

- Dr. Selina Shah, a board-certified sports medicine and internal medicine physician, emphasizes the necessity of diversifying and engaging different muscle groups for optimal health benefits. While the 12-3-30 workout presents a seemingly casual stroll, experts advise approaching it with the same commitment and consideration as any other exercise routine.


- The 12-3-30 workout has undoubtedly gained popularity in the fitness community, offering a straightforward and accessible approach to treadmill exercise. Whether it's the right fit for you depends on your fitness goals, preferences, and overall health. Before starting any new exercise regimen, it's advisable to consult with a healthcare professional or fitness expert to ensure that it aligns with your specific needs and capabilities. As with any fitness trend, consistency and dedication are key to achieving lasting results.
