After about nine months of trial and error, I developed a 20-Minute Workout that combined high-intensity interval training (HIIT) with yoga and without the need for equipment. You can do this workout at home, in a hotel room, or even in your favorite park. Here’s why you should combine yoga and HIIT: At the end of the day, you need to listen to your body and do what works for you. If you live a busy life like most of us do or simply want a quick yet effective workout, you should integrate this type of training into your weekly workout schedule.
