Social media influencer Lauren Giraldo claims to have lost 30 pounds by following this workout trend.
“I’m not a runner, and running on the treadmill was not working for me. I started playing around with the settings, and at the time, my gym’s treadmill had 12 incline as the max. The three miles per hour felt right, like walking, and my grandma had always told me that 30 minutes of exercise a day was all you needed. That’s how the combination started,” she told TODAY.
