My fave tricep movement by a mile, done seated... It is a movement that can realy hit the long head and add a lot of size and volume to your arms, will also stress your elbows big time... Your triceps can push heavy weight, for me doing these too light and your missing out.
I use a cable version now, if you have an adjustable hight pulley, I set it just below shoulder hight and step out it, great stretch and pump, not as good as heavy ez bar, but as close as you can safely get.
