Hi Claire and welcome!
Don't worry, even as an oldie I jumped back on the wagon for the millionth time on Jan 1st but like you didn't want to start reposting until a few days after!
Your plan sounds great, good luck with it!
Do share your ab challenge, I'm intrigued!
Also, join in on the UK Chicks Chat thread, it's normally where most of us 'hang out' although many of the oldies seem to have gone a bit awol, not that I can talk.....! Given that it's Jan though, there are bound to be plenty of new faces and then the few of us that are still around so we'll soon get to know each other and offer plenty of support I'm sure
2013 is going to be MY YEAR! Focusing on good food choices and exercise, the rest will follow!
Taking a break from the scale, but BACK WITH A BANG! When I'm back in the UK in April 2013 I hope to be lower than 168, which is from July 2012ish and the lowest I got before some regaining. Until then, it's all about good food and exercise and no obsessing over numbers!
