If you’ve been watching a lot of fitness videos on TikTok then you might find this 12-3-30 workout pretty familiar. Founded by American social media influencer, Lauren Giraldo, the treadmill workout routine first started when she introduced it on her YouTube channel back in 2019 because she allegedly didn’t enjoy running on a treadmill for 30 minutes but still wanted a good workout. Now, four years down the road, surprisingly, the exercise is still going strong amongst the online community to this date.
For the unacquainted, the 12-3-30 treadmill exercise typically consists of setting your treadmill’s incline level to 12 and walking at a speed of 3 miles per hour for 30 minutes straight.
However, you might need to check if the treadmill that you’re using at the gym or at home has the same settings. Otherwise, if your treadmill can’t go up to 12, you can switch up the settings accordingly by increasing your walking speed, and decreasing your incline.
Personally, I enjoy this more than the usual sprint interval training because there’s no need to constantly change the settings on the treadmill.
To some, you might wonder: Why not just run on the treadmill for half of the time instead of walking for half an hour? Well, the workout was first conceptualised for those who don’t like running on the treadmill, for those who prefer a walking workout, or even if you just want to bump up your heart rate.
Ultimately, the workout is a cardiovascular exercise that’s supposed to work on your lower body. And if you’re planning to try it out by yourself, it’s best that you go for a quick 5-minute warm-up on the treadmill with no incline, to prep your body before intensifying the session.
Not all exercises are meant for everyone and that includes the 12-3-30 workout. And while it does boast some excellent benefits, such as getting your heart rate up, this exercise may not work for everyone. Take, for instance, people with ankle, calf or back problems, or even those who prefer running over walking.
Essentially, it all boils down to your physical ability and comfort level.
A lot of times I find that these trendy, of-the-moment fitness trends are popular just because a well-known celebrity or influencer is endorsing the exercise (Read: Chloe Ting’s viral workout on YouTube).
So, the only way to find out if this workout was worth the hype was to actually try it out for myself, which was what I did for over a week.
At first impression, I realised that it was a relatively easy workout. I mean, it’s just walking up a treadmill for half an hour, how hard could it be right? On top of that, I’m also not the biggest fan of running so I was really curious about how effective this workout was going to be.
And much to my surprise, I was definitely struggling with the exercise. Halfway through my first session, I started to break out in a sweat and my heart rate was steadily going up. And soon enough, when I was nearing the end of the workout, I could barely keep up with the pace.
I tried it for the next few days and it genuinely felt like I was getting stronger, even though it felt like my legs were going to fall off on some days.
But did it help me lose weight? Not really. Generally, like most exercises, coupled with a healthy diet, you will start to notice some changes over time. However, I do think that you would need more than a week to see a significant change in your weight.
Of course, I would say that this 12-3-30 workout is still a great exercise if you’re not a fan of running. I can definitely see myself doing it in the gym at least once a week to get some cardio in. However, it is important to note that this shouldn’t be a replacement for traditional strength training, but it can be a nice addition to your current workout routine.
