Pommel horse - a great triceps and chest exercise?

ive seen gymnasts do something called the pommel horse.. is that an effective triceps and chest exercise for strength and hypertrophy?

Yes, Pommel Horse develops a lot of upper body strength or it needs a lot of upper body strength to do anything on it.

Triceps, shoulders, chest. It's basically a support that moves dynamically and attempts to defy gravity in the case of circles.
