>>I'll second the Michael McCormack (
www.triathloncoach.com) recommendation, especially for the time constrained athlete<<
Another satisfied M2 customer here. I ride my Computrainer religiously, mostly in erg mode these days (without the software, I just adjust wattage during my workout). The M2 workouts keep you focused because they are structured...and the challenge of meeting each interval goal taps into the same competitive spirit that keeps me riding hard on my group rides on the road. I got very strong this year using M2 workouts and I really feel they help me maximize my time. I'm a busy, professional single mom, and the Computrainer gives me the flexibility to keep to a workout schedule all year. I never train more than 12 hours a week and I am continuing to improve.
I find the feel of most other type of trainers difficult to take mentally....the Computrainer is much smoother. And since M2 has an almost endless variety of workouts, I never get bored. I can train in front of the tv w/o losing my focus...if you are working at a certain wattage within a prescribed cadence, you can't cheat....Of course, I do miss a lot of whatever I'm watching!!!!
