Body Rev phase 3 week 12 workout 12 done - and that's me finished with Body Rev. Yippeee! I'm not going to start a new JM before I go on holiday, I'm going to alternate her yoga workouts and take things relatively gently, and then I've ordered Killer Body for when I get back.
ihatethecold, I thought Body Rev was really good - it's a 90-day programme rather than 30, with 12 strength workouts and 3 cardio. (The strength workouts also include cardio intervals.) You do each strength workout for 2 weeks, and each cardio workout for 4 weeks.
The strength workouts come in pairs, for the front and back of the body - so in weeks 1 and 2 you do workout 1, workout 2, cardio 1 and repeat, and then move on to the next set of workouts in weeks 3 and 4. I cheated and did 5 days a week not 6, because I would have lost the will to live if I'd had to get up and do cardio on Saturday mornings. If you're reasonably fit already thanks to the mighty JM, phase 1 is fairly easy.
UnalignedAnt, sorry about your knee. I second NMTZ as an option - the last two circuits are done lying on the floor and shouldn't strain your knees. Pilates is another possibility: a lot of the moves are floor-based and shouldn't put too much pressure on the knee. I have the Darcey Bussell Pilates for Life DVD, which I recommend.
