So I'm competing in a day less than 4 weeks in a push pull and my PR DL without straps is 435 and I just pulled 485 at the end of my workout with straps. In every deadlift workout I do I go double overhand for all of my warm up sets and basically as high as I can, about 315 for 4. Then switch to mixed grip until as high as I can, usually through working sets of 365 to 425 depending on the day and reps. Obviously I need to get my grip to catch up and I've been training it with holds from the rack with 425 and then hang cleans with a fatter olympic bar on my back days and then DB holds and single arm BB holds. My questions are:
What are some other recommendations that might help me push my grip up pretty fast? How many days a week to train it? etc... I just read an andy bolton article and got some ideas about the plate deadlift holds.
I'm using liquid chalk and a pretty worn down bar for deadlifts, don't have any choice at the gym I'm at. Will real chalk and a good bar make a pretty big difference come competing time?
Just to make sure, the bar that is used in competitions is pretty much the standard bar you find in the gym? like not as thick as an "olympic" bar (I call it this because it has more spin and bearings in the end and is just a tad bit thicker than all of the other bars).
Lastly, is there anyone on here that uses a hook grip? I'm contemplating starting a hook grip because I just started deadlifting 6 months ago and since I'm already having grip issues that's not a good sign. Is it expected to be able to hook grip more than a mixed grip? (once I build my thumb up to hooking it) I know oly lifters use it since they have to have double overhand position but I have only seen a few videos with powerlifters with a hook grip
