1. First of all, you must insist. You can add a little more every day until you can reach 40 minutes, because only in this way will you start to burn fat, as you said, it will always work, and persistence will win.

2. Sit-ups ... I suggest you divide into three groups a day, with 50 people in each group (the more, the better ...), but do 50 more before going to bed at night.

3. Chest problem ... I'm a girl, so I don't know much about it ... but as long as I lose weight all over, my chest will naturally lose weight. ...

Let me give you some more advice. ..

1. The so-called breakfast must be eaten. Whole wheat bread and low-fat or skim milk are recommended. You can also have a boiled egg, and you can't eat more for lunch. After that, you can't eat any food, vegetables and fruits until 6 o'clock, but don't eat anything after that, just eat midnight snack.

2. Eat less or try not to eat anything containing starch and fat. The self-control of boys should be ok.

To lose weight healthily, you have to eat and drink, and eating less and exercising more is king.

4. You can put some things like olives around you and take them out when you are really ready ... and eat some nutritious things, bean products and things with high vitamin content.

Never give up halfway. When you think you can't hold on, think about what you will look like after your success ~ ~ Many girls are fascinated by Shuai Shuai.

Well, this process takes about two months, which is very long and painful for people who lose weight, but you must persist. That's how I got here. I reduced from 1 10 to 90, relying on two months of persistence, so come on, I hope you can succeed.
