its all about proportions, Rogan has very short arms, this is why I think he is 5'6 not 5'8
There are plenty men who are 5'7 to 5'9 who don't look short they are short but they dont look like a dwarf mainly because of proportions
This why when a woman is 5'7 or 5'8 she is TALL, she will look much taller than a guy her height mainly due to the limbs and proportion women will have longer limbs where some 5'7 guy could have short arms and stocky making him look shorter. its all about proportion if you are a shorter guy never bulk up get strong lean and muscular not bulky.
That Zac Efron guy looks normal size, he has long arms but he is only 5'7 he admit he is 5'7 barefoot and 5'8 to 5'9 with certain shoes but he looks normal not dwarfish or midget looking
He is lean and muscular but not short and stocky like Rogan so he looks normal even though he is only around 5'7, when you are shorter its better to look like Efron than Rogan stay slimmer and dont bulk up.
