The KTR Outdoor Double Shoulder Shaper is a strong, top-performing fitness unit that not only is able to effectively strengthen and loosen up the shoulder muscles but also, at the same time, provides a very smooth, controlled resistance that can be used by people of any fitness level. The weather-resistant steel construction, anti-corrosive coatings, and ergonomic rotating handles make this double-unit fixture a great choice for two persons to work out simultaneously or for a single user to switch between sides for equal muscle training sessions. The dual-arm device of this machinery naturally directs the circular and upward movements of the shoulder, which in turn results in the strengthening of the deltoid muscles, the increase of the range of the joint, and the development of the coordination of the upper body. The apparatus encourages low-impact, fast-paced movements, which is one of the reasons it leads to higher blood flow in the areas around the shoulder joints—a very important advantage for people who want to get rid of the stiffness that is a result of a sedentary lifestyle or of repetitive physical tasks. Besides, the smooth and synchronized motion pathway lessens the chances of strain, and, therefore, this device is simply great for warm-ups, rehabilitation, or general conditioning. Being a great addition to any park, outdoor gym, or community fitness trail, the KTR Outdoor Double Shoulder Shaper can be described as a perfect combination of function and accessibility, which, in turn, provides its users with a safe and effective way to strengthen the shoulders, upper arms, and upper back while at the same time they are able to breathe the fresh air and take advantage of the open space of an outdoor environment.
