Chin-ups are a back exercise first, but many lifters turn them into an arm-dominant grind. Better intent, setup, and execution help the lats do the job they are built to do.
Chin-up grip is not just a comfort detail. Hand position, shoulder mechanics, and individual structure can all affect how the movement feels and how well it fits your body.
Paused chin-ups reduce momentum, reinforce control, and increase tension where many lifters cheat. This close-neutral-grip variation also gives the shoulders and spine a brief reset at the bottom of each rep.
