I've had the Kurt Kinetic Fluid Trainer for 3 years. It's a trainer, what can I say? It's pretty quiet, though.
I also have the Cyclo-Core program. I bought it 3 years ago, when my husband dropped his gym membership, so we decided to do it together in the winter, even though I still went to spin class. I found the weight training stuff very difficult and I am not in bad shape.I bought the intermediate level program. We lowered the weight levels to do it. The core stuff and yoga is challenging, but good. I use it all of the time, still, for when i don't want to go to the gym. What I didn't realize was the cycling part is NOT on the DVDs. It's just a written program of drills, etc. you follow. There is one yoga/spin class on DVD, but that's it. So, if you are looking for visual stimulation, this is not the program for you, unless it has changed.
