The purpose of training is not to get tired, it's to improve performance. Sometimes, our sprint training sessions will seem too easy to many who are hooked metcon junkies because they're not vomiting or totally smashed at the end of it. The proof is on race day, not at the end of the training session.

It's trivially easy to program a training session to make you tired at the end of the session and aching for days afterwards. Is it going to improve your performance? THAT is the million dollar question
