That depends on whether you have a natural delivery or a caesarean section. If you give birth naturally, you can run for two and a half months after delivery. No problem, don't worry! If it is a caesarean section, it is recommended to do hiking activities three months after delivery. If you want to run more than 6 km/h, it is still recommended to do it half a year after delivery, and the running speed within 5 km/h is also recommended to exercise after 3 months after delivery! I hope I can help you!
