People tell me, my triceps are one of my best bodyparts.
Most overall size I attribute to weighted dips between benches. It works much better for me than weighted dips between parallel bars, the benches give better isolation. Decline dumbell or decline barbell skull crushers are a good bread and butter exercise.
Somehow (maybe due to long arms, I don't get a good feel out of doing close grip bp variations, but they seem to work for most other people).
I got a nice sweeping flare in the long head, and it seems to me that doing some sorta overhead extension is mandatory for that, the 1 arm overhead extension or the kneeling overhead french press with a cambered bar seems to do the job...
