The Viral 12-3-30 Workout Disappointed Me, But I Wasn’t Surprised

If you’ve not heard of the 12-3-30 workout before, it’s pretty self explanatory. The workout is treadmill-based, so it requires most people to get out of their homes and into the gyms — already a positive. It’s also built to be done every single day. Yes, you can still have your rest days, but I would say once you get used to it, this workout could be seen as an active rest.
