I almost lost my hand earlier this year due to an unrelated incident. Since then I have been having problems with.. basically anything that requres the use of my right hand.A fellow gym member decided to teach me how to utilize my strength better by teaching me the grip. It was a bit annoying at first but you get used to it. There is a good website that explains it, I can't post direct links but you can find it on Stronglifts if you Google it.
It's like when I do French curls or skull crushers when I burn out close grip bench I fold in my thumb feels better
