Fwiw, I think curls are important. How much, when, and for whom will vary.
Jouko Ahola, et al - do them (heavy hammer curls) and that's enough of an argument for them as I need.
Yes, Jouko Ahola doing dumbbell hammer curls. Warm up with 20kg. It gets more serious with 40kg. With the 60kg set you're allowed to cheat a little.
