To solve your problem thoroughly, you need to know something.

1.

I read the following comments, and you said you want to lose weight. Then I want to know what your fitness method is? Do you focus on aerobics or strength training? This is very important.

Losing weight is a process of exercise and diet control. Want to know what your diet control has done?
