Calves are genetic. Some have them. Some dont. You would hate me. Ive had good calves without trying, but hey, thats just the way things go with calves. Of course the best way for me to help would be for me to be in the gym with you, watching you train but since we cant do that and the data I have is very limited, what I am going to look at is what you have not said. You said you train them in different ranges and different amounts of time per week. What you have not said is how you train them. So you may do this. I dont know but if not, it  may help. It doesn’t take much to warm them up. Get right to your heaviest weight for 8-10 reps to failure. Go down into a deep stretch, hang there and then drive them up, squeeze and hold, then back down in the deep stretch. NO BOUNCING lol. Sometimes I see a guy get on the calve raise and they use a heavy weight and bounce it up and down in short movements. Dont be that guy. I will look down on you haha. So try changing the way you train them and get the most out of each rep, using no momentum what so ever
