Something has to give here.
The answer to this madness, like so may other answers in matters of strength, is to simply look farther back than Arnold, back before gay men got the idea to masquerade as artistic photographers to the bodybuilding world in droves. Stop when you get back to the 1920's to a guy named Hermann Goerner. Goerner is one of rare strongmen who was roundly respected by nearly every major figure in the fledgling weight training world of his time. Finding information (especially reliable information) about the strongmen and weightlifters of those days is tricky. You almost always find one calling the other a phony. That didn't seem to exist in regard to the big man with the Htiler Moustache. Just about anyone who had contact with him considered him to be the strongest man that ever lived.
...Wait a second! Swing a 110 lbs kettlebell OVERHEAD?
In addition to being proof that kettlebell lifting isn't what it used to be, it's also a great way to get some serious upper body work. If it worked for Goerner, it'll work for you! This is the way that curling should be done: with pressing work. The weight training world is finally beginning to pull it's collective head out of its ass when it comes to neglecting pressing. Back 110 years ago, if you weren't pressing, or at least putting weight overhead somehow, you just weren't strong.
How did this press not hurt like a motherfucker? Perhaps even Russian pot bellies are stronger than American ones!
In other words, do a supinating curl of the weight(s), drop into a deep squat, then press the weight(s )overhead. Then, stand up and do it all over again. I use this one when I'm at home, working in my low-ceiling basement with dumbbbells. Were I to standing press with those, I'd put the weights through the ceiling. Out of anger, the thought has crossed my mind.
How to implement these into a workout is totally up to you. I enjoy pre-written programs about as much as I enjoy the Jersey Shore but I'll share a few ideas anyway. I normally like to do these in a pyramid set, increasing the weight I press and curl as I decrease the reps. Then, decrease the weight and increase the reps. I've also used them as a finisher but if I find out that you're using tiny weights for high reps to tone, well...
Bert Assirati was a fan of this curl-press movement as well. Frankly, if two of the biggest, most powerful men to walk Europe in the 1920's were doing this, I think that's more than enough justification for you to do them as well.
