FAQs

Is the 12-3-30 workout good for weight loss?

It can be a helpful tool for weight loss because it burns calories. However, weight loss primarily happens in the kitchen through a calorie deficit. This workout supports that goal, but isn't a magic solution on its own.

Can beginners do the 12-3-30 workout?

Yes, but beginners must start cautiously. Begin with a lower incline and shorter time, like 5-8% for 10-15 minutes. Slowly increase the incline and duration over several weeks as your fitness improves to avoid injury.

How many calories does the 12-3-30 workout burn?

Calorie burn varies based on your weight, age, and sex. On average, a person may burn between 200 and 300 calories in a 30-minute session. Remember, machine readouts are often estimates.

What if my treadmill doesn’t go to a 12% incline?

Don’t worry. You can adjust. If your max is 10%, simply add a few extra minutes to your walk. Or, you can increase the speed slightly to 3.2 mph at 10% to match the intensity. The principle of challenging incline walking remains the same.
