When I do Wrist curls with the barbell I can do 75lbs for 20 slow reps fine. If I pop on 85lbs, my wrists pop everytime I go down and it does hurt when it pops. Am I forever stuck at 75 even though I don't have any problem doing it? Same thing with reverse wrist curls- at 40lbs I'm fine, 50 it starts popping. What does everyone think?
