Pull-Up Bar

How to adjust

There are no adjustable parts on a fixed bar — the only choice is grip position/width (wide overhand, close underhand, or neutral).

Jump or step up to grip the bar with your chosen grip, hanging with arms fully extended.
Pull your body up until your chin clears the bar, then lower under control back to a full hang.

Check the bar and its mounting are secure and can support your full bodyweight before hanging your full weight from it.
Keep the shoulders slightly active (not fully passive) at the bottom of the hang to protect the shoulder joints.
Check there is clear floor or a box underneath to come down onto before you hang.
The moment you can't make a clean rep or your grip starts slipping, lower under control, get your feet onto the floor or a box, and only then let go — don't grind out one more rep and drop from height.
