Since no one else seems to be throwing it out there, I'm just going to mention that calves are by far the hardest muscles to grow using standard or non-standard training. Generally, getting any results at all (over time not some short term pump shit) is far above average results especially when it comes to someone who started with lagging calves (i.e. not great genetics). Don't be discouraged if this doesn't go your way even if you do everything right. I honestly think your time would be better spent in the squat rack.
