If you like kickboxing, you'd like Turbo Jams. I used to do just the Firm but I lost interest and started slacking off. I decided to give Turbo Jam a try and I loooooove them. they are tougher than I expected and according to my HRM, I burn anywhere from 650-975 calories per workout. Gotta love that! Sounds like you are doing a great job, your weigh in should be a good one:)
