Heather,
DVDs are a great way to mix up your routines. http://www.spinning.com/spinning-sho...os/default.asp BUT, since you are riding at the facility and not at home, a really great resource for sample Spinning profiles is the Spinning Ridebook:http://www.spinning.com/spinning-sho...ories-7321.asp. It's a book filled with 52 pre-designed profiles (class layouts) with technique cues and music suggestions to go along with it. It's designed for Spinning instructors, but you could use it as a guide to ride on your own as well. Here's a sample of one of the profiles called "Core Movement Intervals" that allows you to practice the 5 core movements. Remember to master the seated movements before do Jumps and standing movements.

5 min Seated Flat (warm-up)
3 min Standing Flat
1 min Seated Flat
3 min Jumps
1 min Seated Flat
3 min Seated Climb
1 min Seated Flat
3 min Standing Climb
1 min Seated Flat

Repeat if desired.

Let me know if you have any questions!
