eli5: why do we need to workout to be jacked, why cant our bodies make us naturally shredded
In: 90
The bodies goal is and will always be to maintain homeostasis. This means balance. So if you’re just chilling at home doing nothing in bed your muscles have absolutely no reason to be bigger/stronger/jacked etc. You will actually start to get atrophy, wasting away, especially in your legs if you do absolutely nothing all day.
Once you start hitting the gym your body gets thrown out of homeostasis. The muscle fibers get damaged, lactic acid is released. The body then repairs that damage and adds a little bit extra so that next time you work out you are more prepared. This is why you get super sore the first few days. But the more you work out the less soreness you get. This is the body being able to maintain homeostasis even when working out.
But once that starts to happen you have to up your game and add more weights, more sets, longer running time. To throw yourself out of homeostasis again so when the body repairs itself it becomes even stronger.
