Nice!
Since the triceps are used so much during chest and shoulder workouts, I try not to give them too much attention on their own. Today in fact I'm going to incorporate some triceps training at the end of my shoulder workout, since they'll already be pretty warmed up. Thinking about doing a superset of a pressing or extension exercise (going heavy) followed by something that isolates the triceps, of which I've really been fond of one-arm reverse pushdowns.
