Pull ups are awesome and stuff
There are mainly three types of pull-ups: chin-ups, pull-ups, and neutral-grip pull-ups. Chin-ups involve palms facing towards you, targeting biceps more. Pull-ups involve palms facing away, targeting back and shoulders more. Neutral-grip pull-ups involve palms facing each other, targeting both biceps and back muscles.
The opposite of push-ups is pull-ups.
Wide grip pull-ups target the muscles in the back and shoulders more than normal grip pull-ups. Normal grip pull-ups primarily engage the biceps and forearms. Wide grip pull-ups are generally more challenging and effective for building upper back and shoulder strength, while normal grip pull-ups are better for targeting the biceps and forearms.
