Use the Strauss Chest Expander to add progressive variable weighted resistance to your upper body strengthening programs. Increase the range of motion and positioning of flies, pulls, curls and presses to strengthen and stretch pectoral and arm muscles. A modern take on the classic tool designed for the original bodybuilders, this upper body strength training device offers continual resistance and the ability to target specific muscles for rehabbing upper body injuries and creating increased flexible and mobility. Interchange the cables to customize the resistance and progress in weight as you get stronger. Resistance training uses resistance or force to induce muscular contraction, which builds strength and anaerobic endurance. Resistance exercises also help you increase bone density, improve metabolism and decrease your risk of injury. At Strauss, we provide resistance training equipment that is both innovative and mobile to make your workout routine both effective and convenient. By doing so, our products are easy to use and can provide significant benefits in overall health and well-being by increasing bone, muscle, tendon and ligament strength.
