Did you know that your gains happen outside of the gym, when you are resting? That’s right.
Exercise is just the initial push, a necessary stimulus that forces the body to go through physiological adaptations (getting stronger, building muscle, becoming leaner). For those adaptations to occur, the body requires time to clean up the mess created by your workout session (think of all the by-products left behind) and to repair broken down tissue that was (purposefully) damaged during exercise.
So what happens if we don’t give time for the body to recover?
