All muscles are susceptible to hypertrophy.
I've always had large and vascular forearms, and calves, even before I touched a weight in my life. Of course, they grew quite a bit after some gym time and my buddies always hated how easy it was for me. However, there are some super-strong guys I know that would give their left nut to trade those particular body parts with me. I think some gains can be made with heavy compound movements, but I think you either have them, or you don't. What thinks H&F?
I wasn't born with large calves, but I do come from good genetics. I've worked my ass off to get large, well defined calves because it was something that always impressed me and I think it gives solid, well rounded athletic look. Now they are something that I've had comments on- my buddy says it looks like I have a softball in each leg. My wife digs it too.
This came from destroying them over years of training.
I was actually wondering how you guys do calves, I figured the seated calf raise would "bogus exercise" because you're seated and it's along a generally fixed plane
i did them standing with a DB in each hand last night, I was smoked, how do the rest of you do them?
