Holding my chin

I need some advice. I see all these pictures and videos of people picking up and holding chins like its no big deal. Picking up my chin is always an ordeal. He wiggles and squirms and if I can manage to get him in my arms he flails around like crazy to be put down.

Is it just a matter of him getting used to it? Is it his age (5 months)... Or is it they he will just always hate being held?

Just want to know if there if some Magic trick everyone else is doing. Haha
