I think you&#x27;re being a little nitpicky with my language here. And I in no way implied, &quot;You won&#x27;t get fit without hard work because you won&#x27;t deserve it.&quot; Going for a short walk is still exercise and isn&#x27;t all that hard. I suppose I&#x27;m a little unclear as to what exercises exist that you can put little effort in and get a lot out of.<p>With regards to HIIT, it&#x27;s been pitched as &#x27;get fit quick&#x27;, but without proper training in how to actually push yourself, it&#x27;s kind of a moot point. My only real argument against any of this is that almost every article focuses on the time of the workout instead of the intensity of it and I think it misleads people who are looking for a more efficient way to get a workout in. The time of the workout is really irrelevant, the intensity involved is what makes it so effective. When people see these quick workouts and attempt to implement them, but don&#x27;t see these amazing results that are promised, I&#x27;m sure it&#x27;s incredibly frustrating. That could all be avoided by stating &#x27;Hey, these workouts are really, really, really hard and they will be uncomfortable and you will be gasping for air&#x27;.
