Ok, I need to strengthen my grip for holding wrists while on bottom position. I already do forearm rollers and they're great for forearm thickness. But I have a dumb question about pinch grip. I know many say to pinch 2 plates together and hold as long as possible and increase weight. But can I just take a barbell and pinch it, rather than holding in my palm? Would that work if I lift it up and make sure the thumb and the rest of my fingers are doing the work?
