I followed the TF rotation, well the cardio part, for 10 weeks, I absolutely loved the workouts, but all of a sudden, I just did not want to do them anymore. I never should have done a rotation like that, I get too bored easily, but was truly amazed I made it to 10 weeks before I hit that wall. I did not like any of the strength dvds, but I don't like working with a band for a full 30 minutes, I find it really boring. However, I still am very happy with my purchase, and am just taking a break for a while from these so I can enjoy them again in the future.
