I always like (and rely most on) movements I can “feel” working.
CGB just aren’t one of them, so I only do them once in a blue moon – relying more instead on dips.
Dips and CGB put a lot of the workload on the lateral triceps head.
So if you don’t care for one, try the other - you'll still be hitting a similar area.
do you think it would be smart to work triceps with fast pace...moderate weight (8+ reps)...isolation movements...just to save the elbows?
As has been mentioned, extension work will recruit more of the long head of the triceps – the one that accounts for the most upper arm mass.
Also mentioned here, extensions tend to wipe out many people’s elbows over time.
For many trainers – myself included – a great deal of elbow pain can be reduced / eliminated by going behind the head with the weight.
You can apply that to skull-crushers, overhead db ext., etc.
Bodyweight extensions and kneeling cable extensions bother me the least, and I do a version of them in almost every triceps workout.
One thing I’ve noticed with
any triceps movement is that lowering the weight more slowly also reduces a bit of the pinching in the elbows. Explode up, but slow down some on the negative.
