once you get your trainer…

Go to this website and download a video. It is much more entertaining having a structured session. plus the video footage and music is quite good with amusing commentary. It is alot easier to smash yourself this way I find, you get all the visual cues on screen for intervals etc. so it involves less thinking when you are tired.

the violator is my favourite.

If you are a premium Strava subscriber, go to the training tab and you can watch some of the videos for free (revolver is quite good too). but I dont think they are necessarily their best ones.
