Well I used to have the sticks for calves with no development until I did the heavy weights on the seated calves. I would burn them out sooo bad that I could hadly walk. I did them slow and would hold them a second at the top and then back down slow. Within about 4 months there was a calf. Running has also helped developed them a bit more. I hate having the skinny girl syndrome. Ya know I am now literally ripping out of my clothes... It just taskes time and persistence. Don't give up!
