Personal Trainer Saralyn reacts to the 12-3-30 workout trend. 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.
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.
