most people lift 2 to 4/5 hours a week and dont care about a "diet", eat everything they want yet build very decent physiques, it's not like it's something new.
It's easier for ectos and mesos, but even some endos who are not morbidly obese can do the same and build some muscular mass under their fat.
That's not "bodybuilding", cause these people just want to develop only some bodyparts (usually pecs, chest, calves) , it's more like "weight lifting".
It's healthier than "bodybuilding" as long as it doesnt imply that you re obsessed with your physique and just do it for the practical and health benefits.
Also known as "fitness".
stupid question by the way.
