Hi MandaJean,
I also found Stage 1 to be very long and repetitive -- and at the same time, I found it incredibly rewarding to see and feel progress each time I looked in the mirror or put on my clothes. Miss Jane is right -- the subsequent stages are, thankfully, much shorter

I'm currently chipping away at Stage 5 and was having the same feeling...But when I really took a look at what was "boring" me, I realized it was that I felt I wasn't making the same progress as I did in earlier stages. To an extent this is normal, but it also told me I needed to step up my game and lift heavier to make it more challenging.
To a certain extent, weight lifting is repetitive (as is most other exercise -- to me, anyway), but try to keep your end goals in sight! If it's not too distracting, try listening to some music to pump yourself up, or checking out what other people are doing in the gym -- either for inspiration, or a laugh

Or maybe you can find a workout buddy to help motivate you. Just keep plugging away at it. You're laying the foundation for a new level of overall fitness. You'll quickly become "addicted" to your new body, your new strength and your new confidence!
