Explanation:

The recommended healthy level of physical activity is 30 minutes of moderate exercise for at least five days a week. Moderate refers to it being enough to stimulate the heart and lungs to make it stronger. That is, you have to breathe faster, with a higher heart rate and you will also feel warm.

Children should do at least 60 minutes a day of this type of activity. To avoid gaining weight, you may need to do 40 to 60 minutes five days a week and, if what is intended is to continue losing weight after having already lost something, you should try to do 60 to 90 minutes.
