I go relatively heavy on them (fail on 6-8 reps) because my grip strength affects my bench press, however i have started to feel some moderate pain on my left wrist (joint), it happens when i try to squeeze something. Is this normal? Also are there any other exercises that possibly don’t use the wrist joint as much?
You focus should just be gripping so whatever is most comfortable, I tend to use an pronated grip with a straight bar, but I’ll prefer a bar that lets me use a neutral grip if possible. You’ll want to engage your lats to pull your shoulder blades together and down when you hang to take the load off your shoulders, so whatever grip helps you do that the most.
