12-3-30 Walking Trend: Science-Backed Weight Loss

The 12-3-30 workout is a simple but effective treadmill routine that has gone viral.

You walk at 3 miles per hour with a 12% incline for 30 minutes.

This workout burns more calories and fat compared to flat walking.

It also helps improve heart health and activates muscles like your glutes and core.

Fitness coach Dan Go says it's a good way to get fit without intense gym sessions.

However, Healthline warns that it might be too challenging for beginners and suggests starting with easier exercises first.

The key to success is consistency and adjusting the workout to your fitness level.
