I highly recommend Spinervals. There are more than 20 different DVDs from which to choose---the workouts range from recovery sessions, aerobic base training, strength work on the bike, time trial workouts, sprinting/anaerobic work, endurance sessions, etc. The music, especially in the earlier DVDs, isn't the best, but I've gotten to the point where I don't even hear it. The latest DVDs have an "music off" option, so you can use your own tunes. While Spinervals are about $30 each, I've found them an excellent investment.

I think Coach Troy should consider featuring a Team Estrogen crew in an upcoming DVD.
