Does Curling Increase Bicep Size?!

Yes, but if you want to get bigger, curl more weight with less reps. You shouldn't be able to do more than 5-10 if you're using the correct weight. Do what bodybuilders do, but not what strongmen do. Bodybuilders look big and strong, but they're a lot weaker than the men on strongmen competitions. They may look fat around the waist, but that's muscle protecting the spine. Those men fight mountains while riding on bears.
