You only have one day off to exercise every week. If you exercise hard, you will have too little rest time. In the long run, not only can you not exercise your muscles, but you will strain your muscles. It's best to take a break, or take two days off at the weekend.

If you want to exercise your abdominal muscles, you need to strictly control your diet and you can't relax until your abdominal muscles are obvious. Because abdominal muscles are a very troublesome position, no matter what you eat, you will accumulate fat in your abdomen first.

Snacks are high-calorie foods, and eating them every day will affect the exercise effect. As for how much is a little, for example, after you exercise moderately for an hour, a small piece of chocolate is wasted. But it is ok to eat a little every week, because many people will overeat because they can't stand it.
