My deadlift has stalled because of my grip. I’ve attempted using the hook grip, but it smashes my thumb. I think I have oddly sized fingers, haha. I don’t know, but it hurts just as much, but differently, as doing the standard grip.
I’ve tried using a supinated/pronated grip which seems to work ok.
My main question is, what can I do to strengthen my grip to help pull more weight?
After your deadlift workout, take some weight off the bar, the pull a double overhand rep. Hold for time. Once you can hold it for 90 seconds, up the weight.
I’ve also had grip issues with the deadlift. Suitcase holds with a barbell are pretty good. Ed Coan used to do them for grip. Good news is, at least for me, nothing else builds as fast as grip strength.
I agree with what everyone else has said. One exercise I’d add is pretty much a rack pull. Set the safety pins and barbell right above the knee or a little higher. You want it so that you grab the bar and barely have to move to lock out at the top. This is great to do with a really heavy weight for as long as possible but I’d say no more than 30 seconds and then right afterwards do dead hangs with just body weight.
