Spinning/racing is strong and suitable for young people. Prices range from three or four hundred to three or four thousand online. Personally, I think 1000 or so, and the performance can keep up. Things made of steel are too cheap and fishy. Buying a pile of scrap iron is still a waste. Too expensive is also killing. Tmall is safer than Taobao. Recommend Blue Castle.

Durable or elliptical machine more durable. Elliptical machines are more popular in gymnasiums abroad than treadmills. Domestic acceptance is still not high, elliptical machine has always played a supporting role for knees during exercise, and it is suitable for people of all ages. Recommend Kangle Jia and Wei Bao.
