Chalk helps immensely if you have grip issues. I could barely do 2x315 deadlifting without chalk and was able to go up to 415 on deads by using chalk. It's the best thing if you have grip issues cause it'll help on other lifts as well (barbell bench, rows, pullups, etc).
this is your generic use chalk? or is there a special place to cop?
