Hi all! I'm maintaining now, so not strictly weighing-in, but I still keep an eye on this to see how you're all doing!
Lunarsea - hope you enjoy the gym. I've been going 3x a week for just 6 weeks, and really enjoying it. I feel a lot more energetic and healthier after just 6 weeks; it's made more difference to the way I feel than 6 months of healthy eating/dieting. Our gym instructors are lovely - hope you've got some nice ones too.
Re target weights - just go for what suits you. I'm 5'5", so my healthy BMI is 8.8 - 10.10. I thought 9.7 seemed about right - half-way-ish, but I just can't maintain that without being on an incredibly strict diet all the time. But 9.12 is quite attainable for me, so that's what I'm aiming to stick to. If it comes down a bit as I get fitter, then great!
