The Gold?s Gym 7-in-1 Body Building System comes with everything you need to get a toned, muscular body from the comfort of your home. Your door gym will securely lock into door frames up to 34? wide and provides a challenging upper body workout with a four-position pull-up station that can target your lats, shoulders, back, and biceps with several compound exercises. Rotating push-up handles will isolate your chest and triceps while strengthening hard-to-hit stabilizing muscles - toning your body and improving your lifting capability over time. Condition your core by using included Ab Straps in tandem with your Door Gym - simply slip your arms through the straps and crunch your lower abs into your chest for a powerful abdominal workout. A Toning Wheel provides an additional resource to get the abs of your dreams by using your body weight to strengthen your core muscles and improve your endurance. Follow along with a certified personal trainer on an included workout DVD, and get the full benefit of your bodybuilding system with a professionally-designed exercise chart that outlines a variety of exercises and illustrates proper form.
