The Heavy Duty Easy Gym Doorway Chin-up Pull-up Bar from ProSource provides an inexpensive way to tone and build muscles at home, without large equipment or marring your doorframe with installation screws. Designed to slip into doorways from 24 to 32 inches wide, the Easy Gym can be installed anywhere you have a sturdy doorframe. But, if you have a permanent location in mind, the gym can also be mounted to the wall with the optional, included wall brackets. Thanks to the gym's multi-position design, you will be able to develop your back, chest, shoulders, arms, and abdominal compound muscles with one simple piece of equipment. In addition to traditional pull-ups and chin-ups, the bar allows you to perform closed-wide angle and hammer grips as well as multiple leg raises and oblique curls. Built to last, the Easy Gym is constructed of high-grade steel with ProSource Comfort Grip technology for a secure and pain-free grip. The bar's maximum weight capacity is 300 pounds within a sturdy doorframe.
