Not Cathe and wanted to answer your question.
As far as weight workouts that don't use a barbell, there is Pyramid Upper Body and Cardio and Weights that I know for sure.
However, as long as you have a good selection of dumbbells, you can pretty much do the exact same move with a barbell with dumbbells. When I started with Cathe I only had dumbbells and it went just fine. I eventually bought a barbell set because I wanted to start lifting some pretty heavy weight. Should you decide to eventually purchase a barbell set, here are some suggestions.
1) Walmart- there is a set available at Wal Mart and I believe it is less than $30. However, if you order it online, the shipping charges wind up being more than the set itself so see if you can't buy it at a store.
2) Target- also has a set which I got on sale for $35 (I think it's usually about $50).
3)
www.fitness1st.com- Sells the same set that Cathe uses in the Intensity series, the Troy Lite. It sells for $49.95. Even with shipping it comes in at around $80.
4)
www.amazon.com- Is selling a barbell set and the shipping last time I checked was only $4.95!!!!
HTH,
