Took me my 13th year to get calves - natty training even put 2 inches few months with what’s called nautilus multi machine but never see around no more . Had belt tied to weight stack and steps plus dip chinning part . 10 standing 6 seconds descent on each 4 up ., then bent placing hands on step like donkey with no ready 10 more , then using either dip or chinning part forced reps negative reps to 10 more . My preanabolic days after over decade training put 2 inches on each calf . Plus now always do minimal 600 pounds standing calf raises . Even when I began my AAS journey never equals this again but calves my best too.
