eli5: what is the science behind a hypothetical workout?

382 views

If one were doing 3 sets of 20 push-ups per minute(with a minute or so break between them), that would do more to build strength/muscle than doing 100 push-ups over the course of a few hours, just at a comfortable pace, right? Even though you’re actually doing less? Or am I wrong? Either way, why?

Let’s start with a question. Why does working out grow muscles at all? When you workout you’re actually causing your muscle fibers to become damaged on the microscopic level. As you rest, your body naturally repairs these damaged muscles fibers causing you to become stronger as a result. So, there is a correlation (to a certain extent at least) that causing more microscopic damages to your muscles will have a better result. Now, just doing more of something means nothing, the time in which it is done is also important when you look at putting stress or strain on something. For example, eating 3,000 calories in a day is not that bad, but eating 2,000 calories in one sitting is almost unbearable for most people. So, in short, doing 60 pushups in 3 minutes will cause more microscopic damages to the muscle than doing 100 over the course of 2-3 hours, resulting in more muscles growth (assuming that your body is given adequate rest).
