What Is the 12-3-30 Workout, and Why Is Everyone (Still) Obsessed?

In my two weeks of trying the 12-3-30 workout, I did see some noticeable results. For starters, 12-3-30 started to instill better habits, inspiring me to use my treadmill desk more throughout the day. From a mental health standpoint, I also loved the meditative aspect of the incline walks.

On a physical level, I noticed that walking on a 12 percent incline really targeted my glutes and hamstrings. The 12-3-30 workout made me feel stronger overall, which I noticed when walking up hills, backcountry skiing, and while pulling my kids in a sled. Who knew a simple walking workout would have so many benefits?

Considering my 12-3-30 results, I'll definitely continue to throw the workout into my weekly fitness plan to keep my muscles guessing.
