The Gymstick Door Gym pull-up bar is a durable pull-up bar that can be installed in a doorway, featuring soft grips for a secure hold. Pull-ups effectively develop the muscles in the back and the entire upper body. Besides pull-ups, the bar can also be easily used for hanging exercises as well as stretches for the back and shoulders. The included metal brackets that secure to the door frame ensure the bar stays in place. Thanks to the quick-release feature of the brackets, you can easily remove the pull-up bar from the door when not in use. Note: Do not use in doorways wider than 91 cm.
