In fact, if you want to lose weight, you don't need to buy a treadmill or a fitness card. If you want to run, you can get up at about 6: 30 in the morning and run a few laps in the park, which can not only breathe fresh air, but also burn excess fat in your body quickly. If you apply for a fitness card, you can just exercise your muscles on the machine. There is still a time limit. There are too many ways to really lose weight.
