First of all, if your child is very young, only a few months, then I suggest you not to lose weight. Because the more mothers eat, the more children can have enough food. If the mother loses weight when the child is very young, then the child is likely to be hungry and often cry.
If my mother really wants to exercise at this time, my suggestion is not as good as evening. Don't stay up late, go to bed early, which will make her healthier. Be good to yourself and your children.
Secondly, if the child is older, for example, nearly 6 months. At that time, he could already eat some complementary food. At this time, if mom wants to exercise to lose weight, it is ok. But because of this time, the child still needs to take it from his mother. Nutrition advises mom to lose weight, not too much
Thirdly, if the child is almost one year old, it can actually be weaned. Then mom can completely let go to exercise to lose weight. Usually you can take part in some sports, such as downloading a fitness APP at home and practicing with some tutorials inside. For example, it is ok to support these on a flat plate or roll up the abdomen. However, it is suggested that this mother should focus on exercise to lose weight and not eat less.
Because my woman is very weak after giving birth and needs nutrition to repair her body, exercise can restore her body's function. Never lose weight by being hungry.
To sum up, whether you can exercise to lose weight during lactation mainly depends on your child's age. If the child is too young, then it is recommended that the mother not lose weight at this time, because the child's nutrition is more important. If the child can already eat complementary food, the mother can lose weight appropriately. If the child is close to one year old, then the mother can lose weight freely, but not by starving, but by exercising.
