As someone else said, Uphill Grind -- love to hate it. It is a great workout! I also have Sufforama.... different kind of hate -- it is a good workout, though.
I have Aero Base Builder.... LONG 2 hr workout -- good calorie burner... use a heartrate monitor -- works best that way. Good off season workout.

I also have Lean and Mean, which was the first one I bought. Quick workout, you know you've done something when you're done!
