What to Know About the 12-3-30 Workout | POPSUGAR Fitness

The 12-3-30 workout is done completely on the treadmill and consists of setting the machine's incline to 12 percent, turning up the speed to three miles per hour, and walking for 30 minutes. "Because of its simplicity, this workout routine makes it an easy habit to start and be consistent with," Lindsay Ogden, an NASM-certified personal trainer and small group training experience manager at Life Time, told POPSUGAR. Ogden explained that, in an "ideal situation," a person would incorporate resistance training, stretching, and cardio into their workout routine, performing each type of training roughly three times a week. A treadmill workout — or even a walking workout done on a natural incline, such as hills in your neighborhood — could certainly be a part of that, but try following this trainer-developed workout plan to learn how to better structure your week and achieve your goals.
