You could try post natal Pilates. I'm a mum of four, post natal Pilates teacher and also do post natal personal training. If the exercises are done correctly they are brilliant for getting your gap back together, also the correct exercises help with pelvic floor strength, any postural issues that need attention post birth and also can help you get back on track and feel a bit more human again!!
I'm more than happy to have a chat with you and answer any questions you might have. Michelle 0777 919 3221
