Lose weight: To put it bluntly, losing weight is nothing more than a kind of "consumption". In high-consumption sports, long-distance running is the best method with high efficiency. According to your own situation, I think the gym is not suitable for you to lose weight (reason: 1 The weight loss effect of the equipment is far from that of long-distance running; Treadmill is purely mechanical, far from the spiritual pleasure of morning exercise and road running; Gymnastics in the gym is a low-consumption exercise; The real high-consumption aerobics is competitive aerobics.
Coordination: If you go to the gym, aerobics is very helpful to improve your physical coordination. But instruments and machinery have little influence on this. If you want to practice coordination, I suggest practicing a sport, which one do you like? The focus is on persistent practice and refining technical essentials. Of all the events, Wushu and aerobics can best practice coordination.
I am a sports student and a part-time aerobics instructor. If it helps, I'll give you a few points.
