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?
On the topic of grip strength, I found that eliminating my fifth day (arms) and consolidating it into other days helped a lot. The extra day of rest (4 training, 3 resting) had dramatically improved barbell row and deadlift for me.
Probably don’t need to be solid blocks of training and rest either. I’d imagine 2+1+2+2 would work just as well.
