I'm going to share personal experience with me...
I've worked out my calves forever with NO GROWTH, and I mean, nada, zip, zero. It sucked. It was my lagging muscle by a freaking MILE. Until I started DC workout and a split they have, which has tremendously helped me with my calves improvement. I've seen some REAL changes within months and I can now see my two cav muscles popping up on each side.
Here's my workout and I would suggest this to anyone...
Pick one exercise, whatever it may be. So lets say seated calve raises.
Explode up, 5 second negative on the way down, 5 second stretch when it's overextended at the lowest point. Explode up. That's one rep. Do this for 10 reps or whatever you can manage. This should REALLY wear you out.
Now, add some weight to the exercise, not a lot, some. Explode up, 2 second negative, explode, this is one. Do a rest pause for this. So say, 6, 4, 2 reps, consecutively with merely 10 seconds rest in between.
This has helped me grow them tremendously. Hope it helps.
