I need help. Is it true that there's different body types like endomorphs, etc.? I've heard that they both exist and that they're a myth. I only ask because the argument that says they exist have so many different rules about what you can do as an endomorph in your diet and exercise(one article told me not to try and lift my heaviest. I don't think so...) and it's just so overwhelming. Do you have to change your fitness journey based on your "body type" or is it simply about caloric deficits?
