I've got ok calves and people will say its genetics but truth is I like to train calves and have done so multiple times per week for years
first and foremost you need to train those fuckers and you need to train them hard and often.. don't treat them like secondary muscle group. hit them with a purpose
full range of motion. if half reps on bench press don't count and won't build your chest why do you think half rep bouncing calf raises will build your calves . you need to stretch and contract with intensity and purpose
high frequency.. for me about 3x per week is ideal. you may need 4 or 5.. just hit that shit hard for 10-15 mins with full range of motion and move on to the rest of your workout
standing calf raises are way better then seated calf raises .. the seated calf raise machine mainly works your soleus muscle that surrounds your calf . standing calf raises will hit the main meaty part of the calf itself
vary your rep ranges . do standing calf raises with 315 for 10 reps.. then strip the weight off and do 135 for 25 reps. get a burn and really focus on the contraction.
mind muscle connection.. probably the most important with calves then any other muscle group. really put your mind into that muscle when your training and contract as hard as possible.
don't quit when it burns. when it starts to burn thats when the reps actually begin
anyhow, couple tips for you no calves guys
