I bought myself some new stretch bands to try instead of weights, but I'm not really sure I like them. For some of the moves, they were way more of a workout than using weights and made me realize that maybe I should increase my weight when using dumbells. Overall, I prefer using weights, but having bands adds variety, so I'll probably use them every once in a while.
Shoulders and arms went really well last night. As I said, I ended up lifting more weight than last week. Ab Ripper X didn't go quite as well. I wasn't able to do as many reps as normal before needing to take a break. I think it will be several weeks before I'm finally able to do all of this workout!
