regarding Gripad and other similar glove-like innovation, they have no place in a serious training program. a glove is merely a piece of loose stuff betwn the hand and the bar, reducing grip security and increasing the effective diameter of the bar. Gloves make bars harder to hold on to. and gloves that incorporate a wrist wrap prevent the wrist from getting used to training. the only legit excuse to use a glove is when covering an injury (like a bad cut) where the workout is vital and cannot be done without covering.
You should just work on strengthening your actual grip.
