This picture is an elliptical machine, yours is a commercial product. Elliptical machine is divided into front and back. In terms of exercise intensity, the treadmill is much bigger than this. Magnetic control of elliptical machine adjusts resistance, zero friction and wear of parts, and whole body movement. The display screen can show time, speed, mileage, heat and resistance. Better than a treadmill, because it is also a full-body exercise. If you exercise on the elliptical machine, your feet don't need to leave the pedal, so there is no impact and it won't hurt our knees. This is also the reason why the shock absorption system of high-end treadmill products requires professionalism, but the price is very high. At the same price, you can buy good elliptical machine products, but the treadmill may only buy products with general configuration.
Elliptical machines also have three types: external power supply, self-generating power and battery.
The feedback information of external products will be faster and more accurate.
Self-power generation and battery installation will be slower.
