eli5: why do we need to workout to be jacked, why cant our bodies make us naturally shredded

Along with the other comments, it’s also useful to keep in mind that humans are evolved to favor endurance over muscle strength. Even a ‘weak’ human has muscles that can far outlast many animal species, and some human hobbies like running or even walking marathons would be literally impossible for most other species to perform safely.
You can see exactly the opposite in cats (small or large). They’re evolved to be naturally very muscular and strong for their size (including housecats, which is why they can climb so well), but have very little endurance to the point that they sleep most of the day and are basically unable to perform long chases.
