Answer: Muscle Dysmorphia
Step-by-step explanation:
Muscle dysmorphia (MD) is a subclass of Body dysmorphic disorder (BDD), which encompasses different mental health conditions that have a person becoming fixated on a perceived imperfection in their body. Similarly, people with MD see themselves as not as muscular as they really are, despite many of those who suffer this condition having a build that’s at least average and often more muscular than average. This condition mostly affects men, particularly those who lift weights or participate in bodybuilding.
