Do lots and lots of pushups with varying forms (i.e. regular, military style, diamond) and your tri's will be on fire. You can also add different isolation workouts for tri's, but I find after doing a bunch of sets of different pushups, I can do very little with my triceps because they are smoked.
Curls get the girls
You are 100% right though, smash your triceps and your arms will explode....isolation exercises have their purposes, but yes, compound exercises will benefits much more as a whole.
