This exercise bar is simply amazing. A few people on our staff use this product and it's great for serious training, or when you get a chance. Either way, it can help develop some serious forearm, biciep, back, shoulder, and tricep muscle. Don't forget these also can be used for abs. I use this at least 3 times a day in my home gym. It has helped me build strength one workout at a time. I never knew such a simple product can lead to such success.- Deals in Motion Staff Pull Ups ~ Chin Ups ~ Sit Ups ~ Press Ups ~ and much more... MOUNTING The process is actually quite simple and sturdy. We always recommend to our customers that they use the mounting screws and caps that it comes with, although this can be mounted by just extending the bar and using that pressure to hold. But, we recommend you go through the propers steps of securing. The bar comes with 6 screws...3 for each side. Basically, you screw the caps into the door frame and then proceed to extend the bar into caps. This provides a very secure way for you to do pull-ups and chin-ups.
