Hold The Stretch Until It Breaks, Then Downshift To Partials
Hold the deep tricep stretch for 2 seconds per rep, then drop to 1-second holds as you fatigue instead of stopping at the last full rep.
Sam Sulek says
I hold the bottom stretch of my tricep extension for two seconds on every rep before pulling through. When I can't hold two seconds anymore, I drop the hold to one second instead of ending the set. That position is the hardest part of the rep because my hand is furthest from my elbow there.
Try this
Hold the deepest stretch for two seconds per rep, then shorten the hold as you fatigue instead of racking the weight.
