Biceps size stuck anyone had this issue?

[mrutah]

Ok guys I have 18.5 inch biceps cold when I work them usually around 19. 19 is the biggest I have got them and I was wondering what I could do to get them to 20's or if anyone has had this issues. im currently 5'10 220. And am eating around 4000 cals a day 40/40/20.
Anyone have any input on this?

Maybe try just switching thing up. Sorry not much help but if your stuck than maybe your routine needs to be re-examined.

Go heavier! 3 sets. Remember, when building mass/hypertrophy you want to do 85% of your max weight as your rep weight. Hopefully, that makes sense.
