It's hard with calves because you have to find what works best for you. I am fortunate. My mom has huge calves and she kind of passed them along to me. Mine are not as big as hers but they are cut and veiny. Now don't get me wrong they weren't always that way. I tried hitting them hard once a week, twice a week, even three times a week. I tried one exercise, two, even super sets, plus all kinds of reps ranges. Calves are just like every other muscle you have...you have to figure out what works. Now I know calves are stubborn bastards because they say "fuck you" we walk all day, you can't throw shit at us that we can't handle. Well I finally told them to "shut the fuck up" when I found what worked for me. High reps with as heavy weight I can handle with good form. I do two regular exercises, one double leg, one single leg. The third exercise is a superset. That's it. That is what works for me. Hope you can find what works best for you. Good luck brother.
