After the birth
Exercising after pregnancy is a great way to keep and stay healthy and adapt to your body’s changes.
Keeping active holds many benefits for you after the birth of your baby:
The Physical Activity Guideline infographic from the UK Chief Medical Officers' on the left can also be downloaded here.
As soon as you feel fit and able following delivery you can begin walking small distances to keep active. It is very important to begin doing pelvic floor exercises as soon as possible and to continue to do these for the rest of your life!
It is recommended for all women to have a 6 week check with their GP and at this appointment your GP should advise you if it is safe or not to begin to do high impact activity again – Zumba, running etc. If you have had a caesarean section birth it is likely you may need a longer recovery time.
There are many mum & baby exercise classes in the area which are perfect for easing back into fitness and meeting other mum’s. These can be found at Where are we? | Mumbler Ltd .
If you are exercising following the birth of your baby and you experience feeling faint or dizzy, chest pain, headaches, muscle weakness, calf swelling or pain – STOP EXERCISING AND TAKE MEDICAL ADVICE AS APPROPRIATE.
Following having your baby, it is important to activate and strengthen your abdominal muscles to improve recovery, decrease risk of injury and relieve back pain. The abdominal muscles surround the abdomen, spine, pelvic floor muscles and the lower back muscles.
