I have 8 n half months old baby. After delivery, I had not gained much weight. But during my baby's 8 months, I have gained a lot of weight because I feed him and that's why I ate a lot of food. Now my body has become very stiff and I can't do much work. I get tired doing little work. Now I want to reduce weight, and I am planning to join zumba classes. Is it fine to join zumba classes after my c section delivery?
