Long head envy

Hey Mike, I can see you are well-horseshoed in the tricep department. I can't get my long head to grow. It feels like the lateral head is getting all the benefit and the hypertrophy. What's a good lift or two to emphasize for long head growth? I have the exact garage set up you have except with no cables. 

Thanks JD

JD, Emphasize overhead movements. Here are a bunch of videos where I discuss movements that are staples. http://www.workouttrainer.com/home/videos?q=Triceps
