ArinnSo all this weight or bodyweight training with progressive overload is kind of just a way to communicate to our body and tell it to grow more muscles and strength?
Muscles are incredibly inefficient.
That’s why people that work 12 hour days doing manual labor were “skinny strong”.instead of jacked.
To get huge muscles, we need to trick our bodies into thinking we randomly have to move heavy weights every once and a while.
Part of that is slowly increasing the weight so they muscle rebuilds even bigger otherwise it would just stay the same. If you stop, your body stops wasting the energy for those huge muscles and they get smaller.
inefficient
Shouldn’t that be “efficient”? They will adapt to the minimal required strength for whatever the standard is.
A pound of muscle requires many calories to maintain, more than anything else in your body, by weight.
Aside from fat. Or the brain. Or other organs
No, muscles require the most energy to maintain. Literally at rest, muscle is burning more than any other.
That’s why the body sheds muscle readily if they aren’t used, and why building muscle is so effective for general weight loss.
The body also sheds brain cells if you don’t get enough exercise.
