Ziema G10 Folding Treadmill

Ziema G10 Folding Treadmill is an affordable treadmill that may be a good choice for beginners. It includes a USB port that will keep you motivated and entertained during your workout. This treadmill also includes 8 personal trainer workouts which is considerably less when compared to ProForm 520 ZN’s 18 workout apps. The screen of this treadmill is LCD which means it has clearer display compared to the ProForm 520 ZN. This treadmill has a wider speed range of up to 10.5 mph, compared to the ProForm 520 ZN which can only accelerate from 0-10 mph. This model might be a better option for those who are capable of running up to its maximum speed. However, you may be concerned about the labels on the console of this model because they are written in Chinese characters. We have yet to find out if they have available stock with English labels on them to help make the treadmill more avaliable to a wider audience.

Ziema manufactures other equipment and products aside from treadmills which are sold at reasonable price points.
