When you are learning to climb mountains you don’t start with Mount Everest.
The same way with Olympic weightlifting you don’t get stronger by maxing out every day. In CrossFit based workouts RX is designed to give you a target that you won’t hit all the time.
The reason why you do training at a place like Rebuild, and not normal gym is for the purpose of goal driven workouts. RX in a workout should be an inspirational goal you work towards. The wrong way is think if I can’t RX than what is the point. That is like saying you have been mountain climbing for a few months and you can’t climb Mount Everest so it’s not worth it.
Things that take time to get better at have a better pay off in the end, if it was too easy than there would be not pleasure in achieving it.
