It’s always been a practice of mine to change things up frequently. Besides any benefit in the gym, it helps keep my mind fresh and not complacent.
I feel there’s so truth to the concept. They body is incredibly adaptable to stress and stimulus. Keeping your body on its toes can keep it in an adaptable state.
I did not think about the mental aspect. So true. I think I did it subconsciously because I would get bored if I did not. Then my WOs would suffer.
