I've been trying to work more on building up my triceps more and I've added more isolation lifts rather than compounds (e.i. db bench) to try and add a little more size and shape to my body, namely the scrawny patch of skin on the back of my arm. I've definitely made improvements as far as size and strength but I have a really hard time getting a pump rather than just fatigue in my triceps.
also i have been trying to fiddle around with lifts to put minimal stress on my shoulders which tend to come into play on most of the lifts I've been using. Right now I do some combination of
Tri Ext with rope att.
Reverse grip barbell press
Overhead db extension
I'm looking for any exercises that people have had success with that really isolate the tricep and allow for a good pump if possible. or any advice on lifts I'm already using that i should relentlessly pursue and keep in my routines over time due to their quality.
