eli5: why do we need to workout to be jacked, why cant our bodies make us naturally shredded
In: 90
Humans are designed to only develop the minimal amount of muscle. Muscle cells have the second highest energy use (behind braincells), and that’s not very good for a species that evolved to use brains and endurance to outlast and outsmart its competitors.
So humans have a lot of Myostatin, a muscle inhibitor manufactured by muscle cells. If we had a lot less myostatin we’d grow muscles like gorillas, and we could basically sit around all day and still end up with huge muscles (because that’s their survival strategy. Size and muscle and spend their day chewing on leaves).
