I would say there guarantee is pretty true. If you follow the calendar that came with it, I bet you'll see result in 10 workouts..maybe 15 but it sure doesn't take long. I know that after doing it for 3 months I had lost about 20lbs., and I still felt sore after doing it! So it's a great way to lose weight or tone up. Good Luck!
