Hi Dani! I love Cardio Coach for the same reasons I love Cathe. I really need the direction and motivation. If I just hope on a bike and listen to music I do not push myself, I just cruise along at a nice comfy pace and do nothing at all to improve my heart. Sean, just like Coach Troy in Spinnervals, keeps you aware of exactly what you should be doing, where that heart rate should be, and at the same time cheers you on....in a genuine manner. I am the type that needs the cheering and the structure. The time spent on the bike flys by and when I am done I know I got a good workout.....and the calorie count is always better when I use Cardio Coach. The only downside I can see is the music, I don't mind it.....but it may not be everybodys choice. I only have Vol 2, but he does have a really great sale going on in case you are interested, and of course, you can listen online to all the volumes. Hope that helps a little, Dani.
Take care,
Donna.
