Judging from your height and weight, your figure is still relatively standard. I suggest you get into the habit of exercise first. The way I used to use it is this:

Because abdominal muscles are the only muscles that can be exercised without rest every day, I suggest that you start with 20 sit-ups in each group, 2-3 groups a day, and add 1 to each group every day. It won't take long.

Then chest muscles, push-ups, 20/group, 2-3 groups a day, also add one every day.

Warm-up run 15 minutes. Be sure to warm up and remember.

Stretch, after exercise, leg press, hold hands.

Finally, see if you need to improve the circumference, which requires equipment and nutrition. We'll talk after you get into the habit.
