I love this quote "Unless you try to do something beyond what you have already mastered, you will never grow" by Ronald E. Osborn because it can be applied to your fitness journey or just life in general. I know for me, doing P90X2 has been a challenge, several of the workouts are definitely beyond what I had mastered in P90X. But I know because I am trying, because I am pushing myself, that I will grow that much stronger. Remember to add variety and keep trying to master new things!
