To ask if anyone with a B tummy managed to get rid of it?

[Janice88]

After 3 kids, I have a saggy B tummy. I’m about 6-7 kg over weight and a lot of that is my tummy. I don’t exercise much, apart from walking to work 3 times a week (that’s 2.5 miles a day). If I join a gym and start exercising, or get a personal trainer, is it realistically possible to get a flat tummy?
Has anyone lost their B tummy ?

Thanks all. For those who don’t understand what a B tummy is :

Mine is like the first pic and I’m not pregnant :(
