Have you ever played sports before? I was born in sports before, but if I do less now, I will definitely rebound. Diet is the key issue. I am about your age. I used to have a life buoy, but I lost it. My experience is that there are dietary problems, such as drinking too much beer and eating too much fatty starch? Think for yourself, are there any problems with these? Also, you do less sit-ups. You can try doing three groups every night, 60 in each group. In addition, if you like swimming, you can go swimming. Swimming is the most effective exercise to lose weight. Look what I wrote. I think I can give you the best answer, landlord. This is purely my personal opinion.
