I have several of the Spinervals DVDs. One of the last ones I got was from the new "On The Road" series. It is a training ride in Baltimore county. It's a nice change of pace from the studio spinning class format. I also ride my trainer watching network TV using a HRM. I stay in zone 2 or 3 for about an hour. Also, I stand up when commercials come on. You'll learn to hate the major networks.... Turner in particular can have 4 to 5 minutes of continuous commercials.
