I was wondering if anyone has done an isometric version of the underhand grip cable face pull.
I was laying on the floor supine doing this:
And randomly had a thought about putting my shoulders/hands in a similar position to the end range position for the underhand cable facepull Rusin is demonstrating here:
I made fists with both hands and put them near my ears then I did an isometric contraction by pushing into the floor with my forearms and fists as hard as I could. I could feel my mid/lower traps and rhomboids for the first time despite doing 100-300 underhand cable facepulls a few times per week for a couple months. It felt pretty good.
