Never use the word “should.” “Should” implies failure. If you say, “I should go to the gym today.” You are implying that you won’t. Instead, say “I WILL go to the gym today.”
How did you do in that workout yesterday? “I got 75 reps, but I SHOULD have gotten 80.”
This statement implies failure. You got 75 because that is the most that you could have possibly gotten given your situation at that time. Next time you might be able to do more, but that is because you are in a different situation. You have the advantage of already doing the WOD once and have more knowledge, skill, pacing, confidence, etc…
If you say, “I should have…” you are saying, “I was wrong” or worse, “I didn’t try.” We always give everything we have to every training session. We are Champions. There is no should. The only thing that counts is what you do, not what you should do.
