"When I was pregnant, I actually carried a lot bigger than I'd expected being such a tiny person," says Saffiya Sooliman of her pregnancy five years ago. "I could feel my muscles moving, and I could feel that my body wasn't the same but it didn't feel like my body was just stretching, it felt like things were moving, and I'd always had a firm tummy and a six-pack, so I could just feel that things were moving around.
"Then when I gave birth, at that point, that's when I realised that, okay, I now need to correct this. So I started doing more research into it."
