"On the regular I do mainly treadmill workouts. I'm a huge, huge 12-3-30 supporter. You may or may not know that by now. Obviously, sometimes I do other workouts. This is just like my main, my go-to, my regular, my routine workout," she says at the start of the clip.

Well, the 12-30-30 "Advanced"

"Now you may be thinking, Morgan, I already know what the 12-3-30 is. It's pretty self-explanatory. No, I've been doing it for a while where I have gotten to a new routine with it, with a little bit of different numbers, little bit of change, and I do what I call, 12-3-30 Advanced. So I've worked up to what I'm gonna show you," she says.

First, She Grabs Her iPad and Water

"I really just love the 12-3-30 so much because you can adjust it however you need to fit your needs simply by the click of a button in so many ways," she continues. "Like whether you want more or less incline, more or less speed, more or less time. And incline walking is just such a great form of exercise and it actually helped me lose a lot of weight."

Second, She Queues Up Her Favorite Shows

"I love to watch YouTube, watch Keeping Up with the Kardashians, watch whatever I want and it passes the time," she says. She also explains that she loves a "good walk," but it's not realistic to walk outside because she lives in Wisconsin.

Lap One, She Sticks to the OG 12-3-30

"How I do my numbers is on a lap by lap basis. So I am just going to explain what each lap entails," says Morgan. "First I will get started with the regular 12-3-30, so 12 incline and three speed. And that is what I will start with for my lap one. And we will go from there."

She Starts Alternating Between Increasing the Speed and the Incline by One Increment for the First 6 or So Laps

"Basically starting with the second lap, I alternate between increasing the speed and the incline by one increment. So lap one is the regular 12, incline three speed lap two, I increase the speed to 3.1, lap three, I increased the incline at 12.5, lap four, I increased the speed to 3.2, lap five, I increased the incline to 13 lap six, I increased the speed to 3.3. I stay at 13 incline, 3.3 speed until I complete about six and a half laps. It takes me to 1.65 miles and about 31 minutes and 30 seconds," she says.

Then She Decreases the Incline to 9, and Starts a Cool Down with the Speed at 3.3 But Incline Decreased Every Lap

"Then I decrease the incline to nine, keep the speed the same, I finish out that lap seven from here I start my cool down. So I decrease the incline by one increment every lap. But I keep the speed at 3.3 the whole time until I get closer to four miles. So right before I hit four miles, I end with 4.5 incline and 3.3 speed. Then once I hit four miles, I decrease it to whatever I want for the final, final cool down."

She Builds and Declines

"So basically I start and I build, build, build. And then I have a very long decline and I carry out till four miles. And from there I just really walk slow, take away basically all the incline, take away basically all the speed and just cool it down. And then I'm done," she says.

The 80-Minute Workout Is a "Mental Escape"

"It usually takes me around 80 minutes. So this is a long workout, but that's how I like it. It's kind of like a mental escape," Morgan says.

She Doesn't Hold Onto the Handles

"One thing that is key that I don't do that is challenging when you're first getting used to this workout is I don't hold on to these handles," she reveals. "When I very first started doing this workout, I did, but as I progress, like you get accustomed to not doing it."

She Also Doesn't Stretch much

She also admits that she doesn't stretch a lot. "I don't do any crazy stretches. I mean I just do some stretches. I should probably get a whole stretching routine. That might be nice," she says.

You Can Cut the Workout Shorter

Morgan also points out that you don't have to do a full 80 minutes. "if you're having an off day or just need to cut it short for whatever reason, like you can cut it short. You can lessen the speed, you can lessen the incline, you can customize this however you want," she says.

She Plans on Increasing the Intensity Even More

"Maybe in the future I'll even up it more once I'm more in shape. I am just the biggest 12-2-30 supporter and I credit this a lot to losing weight recently. Like a lot, a lot because this is the main workout I would do. And I don't belong to a gym. So because I have a treadmill at home, which I'm so appreciative of, it's perfect for me," she says.

Walking on an Incline Burns More Fat Than a Flat Surface

Walking on an incline burns more calories than walking fast or even running on a flat surface, which is why many experts suggest upping your incline. A 2013 study even found that walking on a 2 to 7 percent incline increased heart rate by almost 10 percent when compared with running on a flat surface.
