another little tip u can squeeze the bar on you other workouts... benchpress, lat pulls, deads, curls and things like this squeeze it harder than u have to its a subconscious thing and your grip will greatly improve its a static workout it helps your brain connect with the muscles kai greene is always motivating the mind the CNS is greatly forgotten. i was taught this in high school football in out group there was 9th graders bench like 315lbs, squating like 505lbs, and deadlifting all the coach would allow on a 45 pound bar... which was 605lbs plus in time you'll be working your grip and don't even notice thing get a mouth peice gritting your teeth also helps to engage the fight or flight mode. and the weighted, hanging pull-up lock is great afterwards
