Hello. According to your current weight, I suggest you walk for 40 minutes. It doesn't take 40 minutes for the equipment to move, just control it for half an hour. Pay attention to the whole body stretching exercise before and after the treadmill exercise, and exercise your hands and feet, which is the exercise to fully relax your muscles. Also, don't stop running suddenly on the treadmill, and slow down for at least five minutes before getting off the treadmill. Control appetite, eat three meals a day at the ratio of 7: 7: 5, chew slowly. You can lose six to ten pounds a month. Finally, once you start to lose weight, you must stick to it for a long time. Otherwise, the rebound will be serious. I wish you all the best, health, happiness and happiness. Please adopt it. Thank you.
