Judging from your height and weight, your figure is a little fat, so in the process of losing a small belly, you must have some aerobic exercise. You can jog for 30 minutes every exercise (you must be over 30 years old, otherwise you won't consume fat), and then do some exercises specifically for the lower abdomen. If possible, you can do the following training in the gym:

Cycling machine (bicycle fitness equipment) training; Captain's chair (a bench with a 30-degree angle to the ground, you can lie on it and lift your legs for a few seconds to strengthen your abdominal muscles) training; Fitness ball training.

Do sit-ups if you have no conditions. But there are a few points to note,

1 When doing sit-ups, the movements should be in place. At first, we should be divided into several groups, and each group should do a few less.

Sit-ups can stay longer when the upper body is at 45 degrees to the plane, which will strengthen the effect of abdominal muscle exercise.

The frequency of exercise can be three times a week. Excessive exercise will affect the quality of each exercise and reduce the effect.

4. Pay attention to diet and sleep. After high-intensity exercise, you must have enough nutrition intake and sleep to have the best effect.

It's about time. I wish you a healthy and beautiful belly as soon as possible.
