eli5: why do we need to workout to be jacked, why cant our bodies make us naturally shredded
In: 90
Large muscles are a body’s response to a stress, in an attempt to adapt.
Large muscles use a lot of extra energy, and we evolved to be able to conserve as much energy as possible. That is why it is so easy to gain weight and so hard to lose weight.
Your body is constantly trying to optimize energy usage, and if the muscle are not needed, it will shrink them.
