It seems like ever since I took off my first callus doing DL's I can't seem to keep one on. Consistently everytime I deadlift for signifigant volume I end up tearing off the middle finger callus on my switch grip hand. I switch up the hand I use for switch grip, however it feels awkward to me to have my dominant hand as the switch grip and I have trouble knocking out 5 reps without having to regrip. My gym doesnt allow chalk. (I know dont get me started). I try to dry my hands preset and to keep a firm grip on the bar is there anything else I can do?
