How long will it takes to heal a cesarean wound? It is alright to exercise after 7 months of operation?

6 weeks. Typical wound healing is around 6 weeks to achieve good strength of the wound. By 8 weeks post op it is considered safe to return to doing abdominal exercises - like crunches, sit-ups, etc. By 2-4 weeks post-op walking is usually allright. By 7 months wound healing is complete and it is safe to do exercises of any & all kinds.
