#WalkingWorkout

A popular online fitness trend, the 12-3-30 walking workout, has captured attention worldwide, including among Thai fitness enthusiasts. While some praise it as a quick path to stronger legs and better cardiovascular health, experts warn that diving in without preparation can risk injury. The bottom line: gradual progression and mindful movement are essential for sustainable fitness.

The routine involves setting a treadmill to a 12% incline, walking at 3 miles per hour (about 4.8 km/h) for 30 minutes straight. The concept appears simple and has fueled viral videos and success stories. One user reported noticeably stronger legs after a month, though the incline felt daunting at first. Fitness coaches caution that such intensity is not suitable for beginners and can lead to harm if not approached carefully.

A new fitness trend known as the “12-3-30 walking workout” has taken social media by storm, promising a powerful treadmill routine for those seeking a quick path to stronger legs and better cardiovascular health. However, while the workout is generating buzz globally—and attracting interest among Thai fitness enthusiasts—experts warn that jumping into this intense regimen may do more harm than good if not approached carefully. Instead, gradual progression and mindful movement remain central to healthy exercise habits, especially for those looking to avoid injury.
