Take your upper-body workouts home with the Smartios Twister & Expander Set. This all-in-one bundle is engineered for serious athletes and home-gym enthusiasts alike, delivering a full range of resistance to sculpt arms, chest, shoulders and back — all without needing a bulky weight machine. At the heart of the set is the adjustable hydraulic twister bar and Arms Trainer, offering a resistance range from approximately 22 to 440 lbs. With a simple twist of the dial, you dial in the intensity to match your strength level and training goals. Whether you’re warming up, focusing on triceps and forearms, or pushing yourself to heavy loads, you’re covered. Paired with that is the chest/arm expander tool, which brings versatility for push, pull and fly-style motions to engage the pectorals, deltoids, lats and upper body stabilisers. The ergonomic foam-grips ensure safe and comfortable use in every rep. Unlike traditional spring-based expanders that can snap back or wear out, this hydraulic system delivers smooth resistance and more durable performance. The heavy-duty build and robust materials mean this tool is built to last in a home-gym setting. Above all, this bundle is designed for compact spaces. No bulky racks or plates, no large footprint — just a clever, efficient tool to upgrade your strength training at home. Whether you’re a beginner or an expert lifter, the Smartios set adapts as you progress. Come with your user guide, resistance adjustment instructions, and tips to make the most of your set: target triceps, forearms, chest presses, shoulder flies, core twists, and more. Get ready to push new limits — in your own space.
