Riverboat sounds like a good plan - some exercises just don't work for us personally. I have to be careful about some of the abs stuff because of my lower back and do switch some of her abs stuff with others I know I'm okay with.
Well - what other JM DVDs? - how long have you got lol
I think it depends on what you fancy...
Banish Fat Boost Metabolism (BFBM on here) is a fantastic 40 min cardio workout - you will feel nicely roasted and basted by the end 
No More Trouble Zones (NMTZ) is all strength, no cardio - I hate it as it kills me - I tend to welcome cardio as a respite from strength!
If you want to target thighs and bum, her Killer Buns & Thighs DVD is fab - don't be deceived, you will build up a fair sweat on Levels 2 and 3 especially...
Oh and Extreme Shed and Shred (S&S) is also great - not such a hard one, but enjoyable and good for toning. The aim is to work up to doing the 2 levels back to back - so 60 mins.
I'm intentionally not saying much about 6 Week 6 Pack as that is my hardest and I haven't done it for ages!
How do you find Yoga Meltdown - I haven't got it yet, but I'm tempted...
Ponks welcome back! I think holidays can be weirdly exhausting. I'm off to Cornwall in a few weeks (a journey of 2 whole counties lol) and I know it will knacker me but I'll love it...
Well done all the L2 Rippers. And well done on Gingercat with the BR - how much longer do you have to go?
Rest day for me - 3 hours in the dentist chair having reconstruction work done. Stupid twit that I was - had a coffee and more than a pint of water before I went (tend to glug it down in the day) and my bladder nearly had me in tears by the end...had no idea I'd be there for so long ! When I came out the loo afterwards, the receptionist grinned and said "aw, you couldn't manage to tear yourself away from the mirror could you..." Erm, no, I actually couldn't get off the loo - like the eternal font... 
Planning BFBM tomorrow - hope I'm feeling up to it...
Sorry for yet another long post...must learn the art of paraphrasing!
Will check in tomorrow :)
