Beach Body estimates 600 calories per DVD in the program. It all depends on your age, size, weight, and how intense you make the workout. I am 6'2 245 and 32 yrs old. According to my HRM (Heart Rate Monitor) I burn about 800.

Yes, this workout program is very good and does show results in short time period. I personally have a friend who used to be over weight and now is in the best shape of his life thanks to the p90x workout. You can purchase the DVD's at the p90x website.
p90x or insanity
P90x is a workout system. You follow a box set of DVDs that vary by difficulty. P90x reviews would be what other (current or past) users think of the product.
To order the p90x program, one has to directly call the p90x company or order from their website. This is because p90x attaches a "coach" to the customer who is responsible for selling the customer other products and making contact with them.
You can find reviews for Tony Horton's P90X program at http://www.amazon.com/P90X-Hortons-Extreme-Fitness-Workout/product-reviews/B000TG8D6I. It is an excellent program and you can even just purchase individual discs. Many doctors recommend the Core DVD.
Yes, but it would be wise to do lifting on a different day as p90x or else you will over train your muscles. For example, MON-LIFT TUE-P90X WED-LIFT THU-P90X FRI-LIFT SAT-rest/P90X sun-rest/P90X. Remember, rest is just as important as the workout.
