Hi! I haven't done a lot of the workouts others have suggested but ICE Metabolic Total Body is excellent, especially if you're just beginning (although I honestly think this particular ICE DVD is more advanced than intermediate)! Afterburn is good as well but I admit that it's not my favorite; however, it will get your heart pumping and uses weights to make it more metabolic. If you enjoy HiiT you'll love Afterburn! Supercuts and Flex Train are two others that are strength plus cardio and fun to boot. I have two left feet so I avoid the step DVDs but I'm sure they give you great results too!
I wear a heart rate monitor and here are the calories I burned for some of the videos (I'm 5'7 and 140 pounds):
Flex Train: 436 calories
Supercuts: 403 calories
ICE Metabolic Total Body (with abs #1): 549 calories
Ripped with HiiT Upper Body Circuit (with abs #1): 514 calories
XTrain Cardio Leg Blast (with abs #2): 486 calories
ICE Upper Body (with abs #2): 409 calories
Afterburn Express (only 1 round of each set instead of two): 296 (double that so roughly 600 calories)
ICE Boot Camp (with abs #1): 418 calories
Total Body Trisets (Upper Body): 399 calories
Great Glutes (no floor work): 350 calories
Lean Legs & Abs with Barre: 440 calories
ICE Rock'm Sock'm: 418 calories
XTrain All Out Cardio: 384 calories
Calories burned varied but those can be used as guidelines. I'm not super fit cardio-wise (I'm more into strength training) so if you're in better cardiovascular shape you won't burn off as much as I did. My goal after the holiday weekend is to try to pull myself away from the strength videos and get back into a cardio routine. I LOVE Muscle Max, XTrain Bi's & Tri's, XTrain Chest, Back & Shoulders, High Reps, Lift it HiiT it Chest, Shoulders & Triceps, Lift it HiiT it Back, Shoulders & Biceps, Push Pull & Supersets.... OK I'll stop now LOL!
Hope some of this helps!
