Traditionally, new mothers are advised to wait about six to eight weeks after any kind of pregnancy to resume most exercise. During this time, they are usually limited to very gentle activity like walking and diaphragmatic breathing. Recently, doctors have begun allowing women to start exercising sooner than this. However, this does not necessarily apply to women who have had a c-section, as these women still have an incision that needs to heal.
Since different women heal at different speeds, be prepared to wait longer than this minimum time limit if your doctor advises you to do so.

There is never too late to start exercising and get to your best shape.

Your ligaments and joints are much more supple in the months after you give birth, so just be aware of that. It's easier than before pregnancy for new mums to injure themselves by stretching or twisting too much.
You’re more likely to get injured because of a group of hormones called relaxin. Your body produced relaxin in early pregnancy to make the ligaments in the body more elastic.
The downside of relaxin is that it can cause back problems and injuries. Plus its impact on the joints might linger around for up to five months after you have your baby.
If you’re in pain or your postnatal bleeding (lochia) gets heavier or changes colour (becomes pink or red) after activity, you might be doing too much.

I know how exciting it is to spin on the pole again after being pregnant for 9 months. But, it’s important to take it easy and to start off very slowly. You shouldn’t start Pole dancing again until you have clearance from your doctor and are two months postpartum, unless you have been very consistent with activating your transverse abdomius and pelvic floor. On the other hand, if you are a hard core Pole dancer, you can start running again 6 weeks post a vaginal delivery. Just be sure you get your doctor’s permission before you begin.
