I mentioned a couple of times on this forum that my grip is in bad shape. I can deadlift about 150 more pounds with straps than w/o. currently I am focusing on grip twice a week. I do 3-6 sets of double overhand static holds, I do wrist curls and I hold plates with my fingers. The silly gym I go to doesn't have thick bars. I also use grippers sometimes, but how useful are the standard one you get from say Dicks? Any suggestions?
