You know, that idea that “Muscles aren’t built in the gym” is one of those game-changers. It flips the entire script on what we think about strength training. The real magic, the actual growth, happens when you’re asleep on your couch, not when you’re grinding under a barbell.

Meaning
The gym is just the catalyst. The actual construction site for your body is anywhere you’re resting.
Explanation
Look, here’s the thing we all get wrong. When you’re lifting, you’re literally creating microscopic tears in the muscle fibers. That’s the stimulus. But the building part? That’s when your body goes into repair mode, using protein and sleep to patch those tears back up, but stronger and bigger than before. It’s a process called supercompensation. So if you’re not recovering properly, you’re just tearing yourself down over and over without giving your body the time and resources to actually build anything back up. You’re basically a demolition crew that never calls the construction crew.
