The Twister Arm Trainer is a compact, twistable resistance bar for full-body workouts. It uses a heavy-duty steel spring to provide adjustable resistance from about 66 to 110 pounds. You can work your chest, shoulders, arms, back, and even legs with various exercises. The foam grips are comfortable, and the design lets you fold it for storage or travel. It comes with guidance for different workouts. It's a good piece of equipment for adding variety to home workouts, rehab, or when you can't get to the gym. Much more versatile than a simple chest expander. Build strength and endurance without taking up much space.
