The Gymstick Pro chin-up bar can be mounted on both the wall and the ceiling. The bar allows for different types of grips and grip widths, thus providing a great tool for versatile training. The ends of the durable steel bar have rubber grips. When installed on the ceiling, the trainee has more space to do knee lifts as well as other boosting movements. The chin-up bar provides an effective workout for the muscles of the shoulders, arms and back.
