30 Day Ab Challenge

NEWSFLASH: If you eat crepes and pastries and large chunks of white baguette every day, you gain weight. Fast, and in large quantities. 
After a glorious week in France with the Fantastic Four, I'm the heaviest I've ever been.
No bueno.
Last year there were loads of challenges going round, mostly to do with squats and crunches. So I'm jumping - very late - on to this band wagon, to see if it actually makes any difference to my sad excuse for a waistline. 
The first day was easy as I have good core strength, so I did a couple of extra exercises from Maxx's chest and ab challenge (from a different site). I might do it again later, too, and I think I'm going to get my exercise bike back out for the evenings when I just want to watch TV.

I've been struggling to eat healthy for the last few weeks, and my exercise regime has been all or nothing, so I need to be more moderate. I find this difficult in everything I do, which leads to being burnt out and not wanting / having the energy to do anything.
There are a few events coming up over summer, so I'm using them as my targets - not necessarily to weigh a certain amount, but to look more toned and fabulous. I'm tired of talking about how I want to look. I now need to actually do something about it.
These are my targets: 18th June - 30 days away - brother's birthday 27th July - 69 days away - friend's birthday 14th August - 87 days away - my 25th birthday!
And these are my current stats: Weight: ...... I'm actually too embarrassed to admit this right now. Waist: 26 1/2 inches. Hips: 37 inches.
As well as not eating like a 'fat pig' - an explanation will follow in my next post - I'll be working out 2-3 times a week, riding 4-5 times a week (especially training for dressage and showjumping competitions), and running (now I have new trainers).
Depending on how this challenge goes, I will post a before and after, then a before and after on /  around 14th August.
