The EN-Cardio Crosswalker is a workout ergometer that engages both the upper and lower extremities, making high demands on the user’s cardio-respiratory capacity. This machine is suitable for cardiorespiratory-restricted patients as the resistance can be set as low as 5 Watts, and its torque can be kept constant to avoid overload. Patients can rehabilitate safely and comfortably with this machine. The EN-Train concept allows the entire training to be programmed beforehand through a chip card. The machine’s results are monitored through software, and progression and regression are incorporated into the training program. The machine’s features include uniformity in operation, a full-color touchscreen, ergonomic design, wear-resistant eddy-current brake, pulse monitoring through a Sigma Sport chest-strap and built-in receiver, low-noise belt-drive, smart-card technology, gaming mode, and HR-training zones. The machine’s sophisticated and extensively tested interface ensures that anyone can operate it, young or old. With the aid of the EN-Train chip card, everything is automated, but even without it, the machine is easy to operate. The EN-Cardio Crosswalker is an excellent machine for anyone looking for a full-body workout that provides a safe and comfortable rehabilitation option for patients with cardiorespiratory restrictions.
