Hello Vicky! I believe this is a challenging time for you being a mom of two little kids. If you want to get your old body back, acknowledge that it's not easy. You gotta find someone to talk about it with. This someone could also be your monitor, checking on you whether you're doing the things that you're doing to lose weight. Regarding exercise, try working out for less than an hour. And don't do something you hate that you won't be able to sustain it. If you prefer walking, then by all means, walk the weight off, instead of laboring on the bike. When it comes to your eating, I think you know the basics. But one tip I can share with you since I also have a baby and had to get rid of my baby weight, is that you should AVOID DRIVE-THRUS, ORDERING OUT, and JUST PLAIN DINING OUT. If you cook at home, you can control the amount of salt, fat, and sugar on your food.
That's all I can say for now. Hope it helps!!!
