I suggested a spin workout also and would love for cathe to do a spin workout. I use cardio coach now - used to take spin classes at the gym but do all my workouts at home now.
I would also love to see Cathe do some spin DVDs. There are very few challenging and high quality spin DVDs on the market.
Spinervals are the best I've found but there is so much that Cathe could do that could enhance the at home spinning workouts.
I too would love to see a spinning video. It would be great to have multiple challenges (sprints/hills/combos of both) and then recreate the workout blender from the Body Blast series so you could easily mix and match the challenges for a variety of workout options. With Cathe's signature premixes included on the DVD, of course.
