My calves are pretty subborn, I always had troubles bringing them up, and I've tried everything (heavy weight, light weight, high reps, low reps, supersets, every angle/machine imaginable...).
Now I haven't trained them in several weeks, but went onto the stairmill for 20 minutes after every workout. Maybe I'm wrong, but I got the impression that my calves have grown and got a lil more cuts as well.
Is training calves maybe counterproductive when u got shitty calf-genetics, and more cardio might do the job? Think of all the cyclists with great calves, who've never seen a weight-room in their lives...
