What's Happening?
A recent study published in the International Journal of Exercise Science has examined the viral '12-3-30' treadmill workout, popularized by influencer Lauren Giraldo, which involves walking at a 12% incline at three miles per hour for 30 minutes. The study compared this workout to self-paced treadmill running to determine calorie burn and fuel source utilization. Sixteen healthy young adults participated in both workouts, which were adjusted to burn the same number of calories. The study found that running burns calories faster, at approximately 13 calories per minute compared to 10 calories per minute for the '12-3-30' workout. However, the '12-3-30' workout used more fat as a fuel source, with 41% of energy coming from fat compared to 33% during running.

The study underscores the importance of consistency in exercise routines and suggests that personal preference should guide workout choices.
What's Next?
The study's results may prompt further research into the long-term effects of different workout regimens on various populations, including less active individuals. Fitness professionals might use these insights to tailor exercise programs that align with individual health needs and preferences. Additionally, the popularity of the '12-3-30' workout could lead to more fitness trends being scientifically evaluated for their effectiveness and health benefits.
