[Expired]Niceday Elliptical Machine, Cross Trainer with Hyper-Quiet Magnetic Driving System, 16 Resistance Levels, 400LB Weight Limit

: These three are what I mainly use at the gym, because I don't know how to use the others . I think the most practical one is the treadmill. You can run or walk, and adjust the incline and speed. To go a step further, even if you have a dog that needs to lose weight, you can use it. The elliptical machine can only be used for pedaling + resistance and so on, and you have to pay close attention to your posture, otherwise you might even get counterproductive results after exercising . 这三个是我在健身房最主要用的，因为其他的不会我觉得最实用的是跑步机，可以跑可以走，可以调节坡度 速度，再进一步说家里有狗子需要减肥都能用上，椭圆机就只能蹬➕阻力啥的，还得很注意姿势不然还会练完其反效果

回复 @锦鲤上线 : You can grab the handlebar and move along with it, which also engages your shoulders and neck. Alternatively, you can hold onto a fixed part to keep your upper body relatively still. The issue is that over time, your posture tends to slip—your knees might unconsciously drift inward, requiring constant self-adjustment. 胳膊可以抓住那个杆跟着一起动，连带肩颈啥的也在动，也可以抓固定的地方，那就上半身不咋动了，就是蹬着蹬着姿势就不对了，膝盖就会不自觉的往中间靠齐，还得自己调整
