So I already wear leather palmed lifting gloves. Coco butter my hands a couple times a week but from my middle knuckle down opposite of my knuckles on my palms my shits starting to feel/look like sandpaper. Which is odd because I've lifted on and off for the past 6 years and I'm just now starting to get this as of the past few months.

Notably the only thing I've changed is going from high reps to high weight.

Anything different gloves/products I should be using?
