Arms have grown in strength but not size

[V1sual B1nary]

Arms have grown in strength but not size since i started 9-10 months ago, i started curling 10kg dumbells and am now on 18kg ones and my lifts have gone up alot so i know my arms are getting stronger and still are but since i started my arms havnt grown at all. They used to look huge on me at 15.2" 9-10 months ago and are now not looking impressive anymore to the eye and are still at exactly the same measurement as when i started. For about 8 months i was doing 10 reps so this should have been focussing on building more mass?
Not sure why they wont get any bigger any suggestions?

same with me bro. work triceps to the max, cuz biceps like calves and forearms are very difficult to develop unless you focus on them alot.

Maybe eating more? Are you growing elsewhere or is it just your arms? If it's only your arms then maybe you need a new arm routine.

^^^ What he said.

Yeah ive grown elsewhere, everywhere seems to be growing really apart from my upper arms, i think my forearms have grown and as i say my lifts have increased alot on my arms but size wise no gains

Even if you are getting stronger, you need to switch what excersizes you do on a body part to help "shock" it into growing. Your muscles are getting used to the same motion over and over again.

Not only would I suggest some new excersizes, but before that I'd do something like this:

Start off with a dumbbell weight that you can do about 10-12x max, and then you curl until you hit failure. Without rest, grab lower weight dumbbells(example, if you have 45lb dumbells, grab the 40lb dumbbells), and then curl this to failure. Keep going until failure and without a rest break until you've gone to failure on the lowest dumbell weight they have.

That'll be a good shock to start off with going into some new arm excersizes.

Down-the-Rack method.

I once tried the down the rack method. Only problem is I do biceps after back and my biceps get tired out from that so I usually have to do a lot less weight than I'm capable of. I could only do the 20 pounds dumbbell so there wasn't too much room to move down the rack lol.

work triceps more, they make up roughly 60% of your arm mass

10 reps for 8 months???? I wouldnt do 10 reps for 8 weeks mate.

You need to keep changing your rep range to shock the muscles into growth.

Some weeks i hit 6 reps, then evern 15, then down to 8-10. Just mix it up a bit.
