After Doing the 12-3-30 Treadmill Workout For 2 Weeks, I Was Shocked My Glutes Felt This Strong
When I first heard about the 12-3-30 walking workout — an incline walking workout you do on a treadmill — I was only mildly intrigued. I prefer walking in the quiet, hilly woods near my house with my dogs, since it's a great workout for my muscles and heart, and essential for my mental health. But sometimes the weather doesn't cooperate, so the 12-3-30 workout seemed a great indoor workout option.
What Is the 12-3-30 Workout?
The 12-3-30 workout is a treadmill workout where you set the incline to 12 percent, the pace to three miles per hour, and you walk for 30 minutes. Simple, right? Influencer Lauren Giraldo first introduced the 12-3-30 workout on YouTube in 2019, but it didn't become popular until Giraldo posted a TikTok about it in late 2020, crediting it for helping her lose 30 pounds and keep it off for two years. To be honest, that's what interested me: the weight-loss aspect. I was still trying to lose some of the weight I had gained during COVID from two years of stress baking, so I wanted to see how the 12-3-30 workout compared to my other workouts and if it could help me reach my goal.
I Tried the 12-3-30 Workout
I already have a treadmill that I MacGyvered into a walking desk for work, so I used that to try the 12-3-30 workout. I decided to try it for two weeks, doing the workout five times a week, because that's what Giraldo said she did. I wanted to see how this walking workout compared to the rowing, running, and HIIT workouts I'd been doing in the past few months. Could a walking workout really be as effective?
