Shut up and take your legs, of course. Exercise for fat friends is like climbing stairs with dozens of pounds on your back, and then you get hungry faster, eat more and get fat faster after exercise. Fat friends with a body fat rate of over 30% are not recommended to exercise to lose weight, because there is a lot of fat and garbage attached to the blood vessel wall of fat friends, and exercise will accelerate blood circulation, resulting in the attachment on the blood vessel wall falling off, which will easily lead to myocardial infarction or cerebral infarction with the blood flowing to the heart or brain. I suggest that fat friends lose weight first. As long as people lose weight, their legs will naturally relax and they will like sports. Then it's not too late to strengthen your physique and keep fit through exercise.
