How the 12-3-30 workout works
The 12-3-30 is a simple treadmill walk that became popular on social media: set the incline to 12%, the speed to 3 mph (about 4.8 km/h), and walk for 30 minutes.
It's low-impact, needs no skill, and gets your heart rate up through the incline instead of running. That's why so many people stick with it.
How to start
- Build up. New to incline walking? Start at 5 to 8% or 15 to 20 minutes, and add a little each week.
- Don't hold the rails. Holding on takes the work out of it. Slow down instead.
- Plan rest days. Three to five sessions a week is plenty; the calves and shins need recovery.
- Stretch after. Calves and hip flexors work hard on the incline.
