Work Out

Why are black guys so muscular without even having to work out?
Latino men are also kind of like that. But if a white guy doesn’t work out he won’t have any muscle.
that isn’t really true, all humans are made scientifically categorised into 3 groups, each of which has a distinctive look and biology, these are endomorphic, mesomorphic and ectomorphic, most people are rarely strictly one of them and are usually varients between one or two or all three of them, this is what determines their ability to be able to gain muscle mass on the amount of effort put in. a mesorphic requires teh least amount of effort to bulk up muscle while an endomorphic would have a lot of trouble keeping weight off and would need to work much harder than the other 2 body types to be able to gain muscle so in theory anyone that is solely mesorphic will be very muscular in appearence regardless of race as you can clearly see not every single one of each race is fit into one of these body type groups but are diverse between all 3. also, black skin is much better at showing muscle definition, take for example body building, participants in this who are off a fair skinned colour would be able to build just as much muscle as anyone of a darker complexion, however, due to their very light skin tone they would usually either tan their skin with fake tan or they would get their skin painted before an event. this would be because the contrast between the light and darker skin much more clearly woudl show in a darker complexioned partcipant and therefore by darkining themselves they are able to show much more definition. so in answer to you question, no, black guys are not muscular without having to work out however, the ones that are off the mesorphic body type would require little to no excersize in order to tone up just like a white, asian or latino of thsi same body type.
Good Luck, God Bless
