So I had added Preacher curls back into my workout back in December. I had to give them up as my forearms would be in extreme pain after my sets and affect the rest of my workout. The pain went away after a day or so. I took the pain to mean my forearms couldn't hold the weight that I needed to curl. Is that a correct assumption? Thay don't hurt at all if I avoid preachers for that week. I don't see how I can mess the form up on Preachers as your in a very fixed position. I'm open to ideas. I did these all throughout college with great results.
I have since put in 2 excercises designed to strengthen my forearms to see if that helps...
Set 1 - 75x8 (warm up)
Set 2 - 95x8
Set 3 - 115x8
Set 4 - 125x6
