You guys are completely off the mark. Obviously you need to do high intensity workouts the proper way. The higher the intensity, the better you must be at doing the exercise properly. Since you seem to have started working out using high intensity, I assume you did not know how to properly do it. High Intensity is not recommended to beginners. It is a special form of workout. This is why they mention this in the article:
"caution should be taken when prescribing this protocol to individuals who are overweight/obese, detrained, previously injured, or elderly or for individuals with comorbidities. For individuals with hypertension or heart disease, the isometric exercises (wall sit, plank, and side plank) are not recommended."
Obviously, for beginners, something with less intensity, and a higher tolerance for mistake will have better results. While you learn how to properly do exercise, and build a core foundation, that will later allow you to move to high intensity. The reason you would want to later move to high intensity, is for either lack of time, in which case, you will need the shortest workout with the highest fitness accomplishments. Or for improved oxygen flow levels and decreased body fat, which high intensity is often better at than other types of workout, no matter how much of it.
The workout described in this article, is one routine, you should not be doing it ad vitam eternam, it serves as an example, and you already need to be in a certain fitness level to perform it properly.
