Although it is not out yet, STS should help with the boredom, I think it has something like 41 videos, you do 3 different weight workouts a week for 3 months, and do whatever cardio you want for the other days. She has tons of info on the STS program on the website and in the STS blog. The intensity of the weights you will use will change each month as well.
I'm not nearly as familiar with all of the videos like others on this board, but many of them come with pre-mixes that mix up the videos for you, some even combine two different workouts into one, like Kick, punch, crunch and Legs and Glutes has great combo premixes. I know the Muscle Max has premixes, not sure about Gym Styles, I think with GS you can do your own mixing and matching by chapter.
