What is the 12-3-30 Workout?

Walking treadmill workouts are an easy way to jumpstart a new fitness routine or add variety to an established one. One of the most popular routines is the 12-3-30 treadmill workout, which continues to be a fan favorite since it went viral in 2020.

The workout is simple: Set the treadmill to an incline of 12 (or lower — choose a challenging incline for your fitness level!) at a speed of 3 miles per hour and walk for 30 minutes. The routine doesn’t require a lot of time, but if done consistently it can improve endurance and aid in weight loss. One of the reasons why it is so popular is that it can deliver these results with absolutely no running required!

Walking is lower-impact and less likely to cause injury than running, and has many important benefits, such as lowering blood pressure and cholesterol, boosting metabolism, improving mental health by reducing anxiety and depression, and even lowering the risk of some cancers. The 12-3-30 trend took off when health and beauty influencer Lauren Giraldo posted about it on YouTube in 2019 and then again on Tiktok in 2020, sharing that the workout helped her lose 30 pounds and keep it off.
