I'm waiting for my month 5 DVD to arrive any day now, so I obviously like the program.

Well, I like the strength training part that is. The cardio portion is not my favorite as I cannot doing jumping and higher impact things due to ankle and knee medical issues and all of the cardio sessions but one had a lot of that in it.
Consistency is key. You really do need to be able to do the strength portion 3 days a week in order to be ready for the next session/ DVD. Also, make sure you don't pick too challenging of a starting level. You can choose from levels 1-4, with 4 being the toughest and one being beginner. I picked three and now am rather regretting it, but I refuse to give up.
