you wanna train widehand grip pullups? simple.
just keep doing it.
however, if somehow you feel pain in your shoulder/back areas, then
its time you head to the gym. the most fundamental body parts you
must do in order to improve your pull ups is of course the lats
pull-down machine, as well as your shoulders.
when you're doing the lats pull-down, grip the bar widely, just
like when you do the widehand grip pull up. pull down, hold it for
a second or two, then slowly release, and repeat all over.
last but not least, your forearm is very important as well. don't
forget to train that.
