Without a doubt, the 12-3-30 workout is an effective exercise routine that's here to stay. As the fitness landscape evolves, the 12-3-30 workout remains a practical option for a well-rounded fitness plan.
The 12-3-20 method is a viral treadmill routine coined by fitness influencer Lauren Giraldo, who lost 30 pounds with this method. So what exactly is it? You simply get on a treadmill, set the incline to 12 percent, and walk for 30 minutes at 3 miles per hour.

To recap, start with low inclines (1-5%) if you're a beginner, and gradually increase to intermediate levels (6-10%) as your fitness improves. Advanced walkers can challenge themselves with inclines of 11-15% to maximize calorie burn and muscle engagement.
The best walking speed for fat loss is usually between 3 to 4 miles per hour. This pace is brisk enough to increase your heart rate and calorie burn, making it effective for fat loss.
