The 12-3-30 workout is a cardio-based fitness routine that involves walking on an incline for 30 minutes.
The workout was popularized by Lauren Giraldo, a social media influencer, who claims to have lost 30 pounds in three months by doing the routine.
The workout is designed to burn calories, improve cardiovascular health, and tone the lower body.
To do the workout, you need a treadmill with an incline feature. Set the incline to 12%, walk at a speed of 3 mph for 30 minutes.
The workout can be modified to suit different fitness levels by adjusting the incline, speed, and duration.
To get the most out of the workout, it is recommended to do it three times a week and combine it with strength training and a healthy diet.
While the 12-3-30 workout can be an effective way to improve fitness, it is important to consult a doctor before starting any new exercise routine.
