Cardio-Friendly 12-3-30 Workout.

The 12-3-30 workout is a popular cardio routine that involves walking on a treadmill at an incline for 30 minutes.

It was created by Lauren Giraldo, a social media influencer, and has gained popularity due to its effectiveness and simplicity.

To make the workout more challenging, you can increase the incline or speed of the treadmill.

Adding weights to your routine can also help to increase the intensity and provide a full-body workout.


Incorporating intervals of high-intensity exercise, such as sprints or jumping jacks, can help to boost your heart rate and burn more calories.

To prevent boredom and keep your body guessing, you can switch up the type of cardio exercise you do, such as cycling or rowing.
