Two per week max - I can go for that. But I still have to get on the cussed thing on the days I don't commute - my bargain with myself. I just may adjust the intensity of my workouts a bit - maybe the days past two or three of the videos, I will just spin an hour whilst watching the news. But 6-800 calories per hour was in the realm of what I was thinking might be the amount. I'm just not able to afford the powermeter right now, but I do like the fact that we can get one from Kurt that will work with the trainer.
The trainer is hateful, but I do like the fact that I can make an hour or so of it fit into my day, where on a weekend my club rides usually eat 5 hours or more of the day by the time I get there, ride, and then get home.
