Does the 12-3-30 workout actually work? Let’s talk science.
Let’s get real. Viral trends are fun, but does TikTok’s Viral 12-3-30 Workout actually deliver?
# 1. It Burns Calories—But How Much?
Walking uphill is no joke. You’re engaging your glutes, hamstrings, calves, and core more than flat-surface walking. On average:
-
A 150-pound person can burn 200–300 calories in 30 minutes at a 12% incline of 3 mph.
-
The incline adds resistance, making your body work harder without adding high impact.
It’s not a walk in the park!
# 2. Great for Cardiovascular Health
This steady-state cardio builds endurance and helps.
Not bad for a 30-minute walk, right?
# 3. Weight Loss and Fat Burn Potential
Consistency is key. Doing the 12-3-30 workout 4 to 5 times a week can help you lose fat. Pairing it with a balanced diet creates a caloric deficit, which is key for fat loss.
But wait—if your diet is all over the place, no amount of incline walking is going to outpace a daily pint of ice cream.
