But a popular new workout trend may be a great place to start your fitness journey. The 12-3-30 workout is both beginner-friendly and helpful for meeting fitness goals. On TikTok, the "12330" hashtag has over 400 million views, featuring videos of users walking uphill on treadmills. "Because it's a fitness trend, it spurs people to be consistent with their workout, [and] consistency is always the key with a workout." Lauren Giraldo, who coined the term "12-3-30 workout" in 2019, says she lost and has kept nearly 30 pounds off using the exercise in the span of two years, according to a TikTok video she posted in 2020.
