Remember when Lauren Giraldo broke the internet with a 12-3-30 workout regimen, and the entire social media went gaga over it. Well, that still hasn’t changed. What started as a viral fitness challenge has stuck around long after most internet trends fell off the radar. 

Why is it still relevant today? Unlike other complicated workout routines, 12-3-30 is simple and gets you moving, which is exactly why so many people are still talking about it and following it. 

What Is the 12-3-30 Workout?

Treadmill incline: 12%

Speed: 3 mph

Duration: 30 minutes 

Rather than investing your time, money, and effort in complicated equipment, you choose to follow a simple treadmill setting to complete your workout goals. 

Why Is It Still Trending?

The 12-3-30 workout did not stay for its popularity but for its ease and efficiency. Think about it: It fits busy schedules, feels more achievable than intense HIIT workouts, is beginner-friendly, is easy to remember, does not require running, and is a great way to build consistency. 

While most fitness routines require you to engage your entire being, the 12-3-30 workout leaves room for additional relaxing activities like listening to music or podcasts, or simply catching up on a book. 

Does It Actually Work?

While it’s not a complete fitness routine, the 12-3-30 workout does improve cardiovascular fitness, helps burn calories, strengthens lower-body muscles, supports weight management when combined with a balanced diet, and is easier on the joints. Use WHOOP wearables to truly track your vitals, heart rate, and strain, not just calorie burn. 

Ultimately, the result may vary from person to person, but for someone who’s looking for an easier way into the fitness world, this could be a great routine. 

Should You Try It?

If you’re looking for an easy way to burn calories and become more active, the 12-3-30 workout can be a great way to start. Although it cannot replace strength training, consistency and discipline can give steady results.
