I have a lot of different "as seen on TV" kinds of products since I live out in the middle of nowhere and get bored easily. BTW, if you want a free daily super kickass workout try the daily workout at crossfit.com (they have modifications for different levels of fitness and women and children), based on Tabata, which I'm convinced is the best workout I've ever had. Anyway no matter what else I buy I always use my free weights and Bow Flex. I have a Total Gym and really like it, except that I outgrew it. My naturopath recommended it to me when I had a lot of weight to lose as it takes weight off the joints. It's also good for people who have arthiritis. Mostly I've bought exercise DVD's because I like a lot of variety there and highly recommend anything from Beachbody.
Turbo Jam is my absolute favorite. Chalene Johnson is great and the music is the best I've heard for workouts either on DVD or at a live class. Cardio Pary Mix 2 is my personal favorite but they're all good. There's a 30 minute one that's aerobic and anaerobic that will kick your butt. Turbo Jam combines kickboxing, Capoeira, body sculpting and dance. Very fun and I've never gotten bored.
Next would probably be any of the Tony Horton videos. P90X is excellent and does work. I tend to stick with it if they're challenging and this definitely is. He's also got a 10 minute workout series (total body, abs, upper body, lower body, core, etc.) I do when I'm feeling lazy or short on time. Even when I'm lazy I can usually talk myself into a 10-minute hyper-intense workout then I'm usually motivated enough to do more.
Slim in 6, Hip Hop Abs & Yoga Booty Ballet, and Carmen Electra's Aerobic Strip Tease are okay and I use them occasionally. Slim in 6's basic workout is on the boring side but the advanced ones are fun for a change of pace. She uses workout bands for part of the routine and they're more effective than I thought they'd be. The Carmen Electra one is a 6 series set. The first one is pretty basic but the other ones aren't bad. There's some pilates inspired core workouts and some of the dance routines are fun. The lap dance is a surprisingly good workout.
