Absolute beginner and very unfit - fitness dvd suggestions please

[Curlylox]

As well as a dodgy back and knee but surprisingly I do have good coordination Was looking at Davina's but she has quite a few so not sure what's best, also would be happy for any recommendations please

Good old Mr Motivator. He did one with several short sections you could put together into your own workout. I get easily bored, so I thought it was great I could choose to do a 'bums and tums', followed by the 'thighs', followed by 'cardio', and then do a completely different set of exercises the next day.
Mr M is cheesy-beyond-cheese and still wearing dodgy neon lycra , but the workout's fantastic and just enough to get you puffing without completely knackering you. (If you can handle the dodgy music, that is!)

Thanks poddy Mr Motivator - what a blast from the past

I have one it is called 'Davina my three 30 minute workouts .Pump cardiobox core stability'
I wouldn't recommend that one.I have done it twice and hurt my knee both times (normally no problems with my joints.Fortunately it was better after a day or so by using ice uimmediately and a compresssion bandage ).
I have been doing a Martine McCutcheon one and that is quite good.Quite easy in terms of intensity but quite dancey.
I also tried a very old Lizzy Webb (the Green Goddess) who was on BBC breakfast time TV while MrM was on ITV .Another blast from on the past
