Ok, i decided i should do this cause i really gotta loose this weight so my back doesnt hurt anymore! And for other reasons too of course but ykwim?

Im haveing a hard time trying to get motivated though. I was going to buy myself a treadmill but that could be a while off yet. I cant go for a walk because its so hilly around here and yep that may seem lazy but my knees/ankles and hills dont mix due to damage from playing netball when i was a kid. Also have no idea on diet. I am breastfeeding so not sure what i should be doing there either.
