A good diet, walking, pelvic floor therapy (helps you learn to breath and reconnect to your core which in turn helps with pretty much everything!!)
Strengthening your core and breathing exercises as well as watching what you eat and walking more has helped me
I follow caesarean phoenix who specialises in this, there’s a lot more to it than just exercise! I’d recommend checking it her out. She does free and low cost courses too x
A healthy diet and lots of walking
