Resistance bands for abdominal workout?

[TotalConfucius]

I am an apple shape and carrying about 1.5stone too much. Recently lost half a stone and this is ongoing. Really happy about my diet, enjoying my food and have fallen into a nice routine of cardio and interval training. Losing only about 1lb a week but that's ok! Slowly but surely. But whilst the diet and exercise are working from the outside in, I'd like to do a little work from the inside out, so to speak - so that as the fat slowly disappears, there might be a slightest trace of abdominals to see! I've lost 4inches round the middle over the last couple of months, but have another 4 to go. I once had muscles and on my upper arms and thighs they are swiftly returning, but my lower trunk has a long way to go.
I have a set of resistance bands. Can anyone recommend a YouTube video or other resource with an appropriate set of exercises I could do at home?

I'm sitting in on this one, I have been googling your thread header all week. Just put a routine together off you tube but I'm struggling, much prefer exercise bike, skipping , swimming and weights, can I linger please op? (friendly wave)

Well we're not getting much help are we!
I've tried some YouTube videos this evening, I'm not really 'feeling it' yet. Hopefully tomorrow I'll have time to put together a bit of a mash-up of several exercises with my own little warm up and cool down. I'm on a limited budget at the moment so no gym membership and can only afford two Aqua classes a week.
It's so annoying - my upper arms and thighs are totally back in shape now, just these abs to sort out!
