here is what I posted on beginner forum recently

I don't like riding on the trainer, but it's better than nothing when Mother Nature won't allow me to get outside. I try to split my time half and half with trainer and treadmill so that I don't get tired of either one, and I vary my workouts a bit.
Good luck
Try this and let us know if it helps

Trainers are very boring if you jump on and spin. What you should be doing on the trainer is a *program* of hard exercises then the time flies because you *suffer* like you are meant to. If you are not suffering on the trainer you are wasting your time.
For example here is what I got from a cycling coach and I promise this will make you suffer - intervals/sprints. Don't cheat. Suffer!
12 * 5 sec sprints, 30 seconds recovery between each sprint
3 min easy spinning at end
6 * 10 sec, 60 seconds recovery between each
3 min easy spinning at end
4 * 15 sec sprints with 90 sec recovery between each
5 min of easy spinning at end
repeat above set total of 3 times, should take 75-90 min of suffering, I promise.
Try two or three times per week and then tell me if riding a trainer is boring 8^)
Note: by Sprint above I mean going ~110-120rpm, flat out hard. Think last 200 metres of Le Tour's bunch sprint end of a stage and you get the idea. You need a computer with cadence and with a seconds time display for this to work well.
