Adjustable Resistance Chest Exerciser, Arm Machine, Upper Body Trainer

Build strength anywhere without bulky equipment. The A-System is a power-twister style chest exerciser with adjustable resistance, so you can match the load to your current level and steadily progress over time. Squeeze for chest and shoulder work, hold isometrics to light up the triceps and forearms, and perform controlled reps to develop pressing power across the upper body. A durable all-metal frame and rubber-covered grips provide stability and comfort, while the spring is enclosed inside the chassis to minimize the usual pinching and hot spots seen with exposed-spring devices. When you’re finished, it slips into a drawer or gym bag—no cables, plates, or batteries required. What’s in the box: A-System adjustable-resistance chest exerciser.
