In today’s Dear Mark, I’m tackling a reader’s question regarding a new workout that’s apparently all the rage on social media. I’m not much for hopping on viral fitness trends myself, but I’m always interested in keeping my finger on the pulse of what people are doing in the name of health, strength, and weight loss. You never know when the next truly great thing is going to come along, right?
Let’s get into it:
I’m seeing a new fitness trend all over my TikTok: “12-3-30.” Other users are claiming it changed their bodies in just a month, and I’m tempted to try it, but as far as I can tell it’s just… walking uphill? Is this trend too good to be true or worth trying? Do you think something like this could be considered “primal”?
Thanks for asking—and for thinking that I might be hip enough to already know about a TikTok trend! As a general rule, if a “get fit quick” scheme seems too good to be true, it probably is. However, let’s not discredit the actual value this trend might hold without examining it more closely.
What is the 12-3-30?
A quick dive into Google explains the “12-3-30,” aka the 12.3.30 treadmill routine, is walking at a 12 percent incline at 3mph on a treadmill for 30 minutes. Credited to influencer Lauren Giraldo, this workout’s short time frame and relative ease have piqued people’s interest. I’m sure the testimonials from people claiming to have made big physique gains in a short time don’t hurt either.
Before I get into the meat of this post, let’s make one thing clear: You should stay active while fasting. You shouldn’t just sit around. You shouldn’t give up. It’s actually imperative that you exercise while fasting.
Everything we do, or don’t do, sends a message. If you stay sedentary during a fast, you’re telling your body several bad messages.
