long head tricep exercise
I need a recommendation for a new exercise to stimulate the long head of the tricep. Tricep movements behind the head or overhead seem to work the long head the most. What I have in mind is doing a ez bar overhead french curl similar to the picture below.

I would preferably rather do this sitting down. Now I would do this exact exercise seated, but I'm not sure how to handle going to failure (besides asking for a spot, which is not what I'm looking for here.)
My question: Can anyone think of a good way to set up this exercise and have a safety rack or something to help when going to failure? Or is there an alternative method that might be better such as cables or something else. I'm not really interested in the dumbbell version though.
Thanks
