- The viral “12-3-30” workout involves setting a treadmill to 12 percent incline at 3 miles per hour and walking on it for 30 minutes.
- Experts say that the workout provides good exercise, but it doesn’t offer unique benefits versus other cardio routines.
- Those who haven’t been working out should build up to the workout.
- Cardiovascular exercise is associated with better long-term health outcomes.
- Walking or running is excellent for cardio health, but resistance training is also recommended in order to get a complete workout.
Trend followers may have noticed that there’s a new cardio workout that’s gone viral — one that may have people dusting off their old treadmills.
Lauren Giraldo, a social media personality, first shared her “12-3-30” workout on YouTube in late 2019, and then again on TikTok last November.
The workout is elegant in its simplicity, getting its name from its core concept: set a treadmill to an incline of 12 at a speed of 3 miles per hour, and then walk for 30 minutes.
Giraldo explained in her videos that the workout is a “game changer” for her, saying that it’s a way to stay fit at home for those who aren’t motivated to go to the gym.
Now, in the midst of the COVID-19 pandemic that’s seen many gyms shut down or reduce capacity, home-based workouts are more relevant than ever.
While Giraldo’s videos have garnered millions of views, it’s important to note that she’s an influencer, not a personal trainer or a doctor.
