I think the weight loss effect of treadmill will be more obvious. In fact, I have struggled with a similar question before, that is, which is better, the treadmill or the elliptical machine. I have also asked many coaches, and I have been to the gym to experience it. Obviously, because the training intensity of the treadmill is much higher, it will consume more energy, so the weight loss effect will be better. I also followed the advice of my fitness coach and bought a high-powered treadmill in Marseille. Although you may not use up all the power of the treadmill, you can't run that fast. In fact, the exercise intensity of skiing machines and elliptical machines in our hospital is relatively low, so it is certain that the treadmill has a better weight loss effect.
