I had shit calves until about a year ago, they're not pro level or anything like that but they look alot better than they used to. Even if I totally decide DC training blows in the future I'll always train my calves using DC's methods, weight as heavy as you can handle for 12-15 reps, every rep is done with a nice slow negative down into a deep stretch, hold the stretch for a slow 15 count and expolde up. You might want to start a little lighter than you think you can cause it's intense. I use movements where my legs are straight-Donkeys, Standing, calf sled, toe press on the leg press machines, etc. Constantly try to add weight once you can't get 12 reps on a movement drop it and pic a new one. I do one movement a workout, training them once a week on week one and twice a week on week 2 and then repeat. also after I fail I stop, shake my calves out for about 10 seconds and start doing partials until I literally can't budge the weight at all.
I hope that makes sense, if it doesn't let me know and I'll type up something that describes it a little better.
