My situation is similar to yours. There are two ways to overcome your present situation:

First, try to like some ball games, such as table tennis, badminton or tennis. As long as you like ball games, you will buy rackets, find partners and find venues. Furthermore, you can take part in this sport every week, gradually realize the advantages of this sport, make you more addicted to it, and thus enter a virtuous circle of persistent exercise.

Second, make an excel spreadsheet on the computer and choose some exercise items by yourself, such as walking 10 minutes, jogging 10 minutes and doing 20 sit-ups. Make a score for each item, for example, if you can walk every five minutes, you will get 2 points, and if you jog every five minutes, you will get 5 points, so that you can record it on this form every day. Count the average daily score of this week every week, and watch your average daily score rise slowly every week, and you will certainly have a good sense of accomplishment, which will inspire and promote your exercise day after day.
