Myth: The more sore you are, the better the workout you got.
Muscle soreness is more an indication of using your muscles in a different way than usual. Everyone’s different: some people feel sore very easily, and others never feel sore. Just because you’re not really sore doesn’t mean you didn’t get in a great, effective workout. The most important questions to ask yourself are: did you use good form with the appropriate weight for the exercise? Did you allow yourself time to recover between sets and between workouts? Did you enjoy the exercise?
