It&#x27;s a clickbaity title, because it&#x27;s not really one total minute of exercise. What this is unraveling is the benefits of HIIT (high intensity interval training). They did a very basic and very minimal form of intervals, because they tested on a population of untrained, unadapted individuals. They basically did a:<p>* 2 minute warmup<p>* 20 seconds all out sprint<p>* 120 seconds of slow pace to catch your breath<p>* repeat 2 more times<p>So in total, the &quot;hard work&quot; was 1 minute, but you&#x27;re actually active and in the gym for about 10-11 minutes.<p>The benefit here is the metabolic boost from strenuous work lasts much longer than steady-state cardio, and this has been observed in previous studies.<p>The problem is that humans are incredibly adaptable - so 1 minute of hard exercise cannot be applied indefinitely. You will need to increase that time in order to see continuous benefits, as well as vary the amount of strenuous exercise that is continuously performed. Anyone who has never trained before is going to see benefit from some physical activity, but as soon as they are adapted, the benefits disappear without progressive loading.
